Answer the following multiple choice question by selecting the correct option.
Context: First find the age gap between the older brother and sister by subtracting the earlier birth year from the later: 1936 - 1932 = <<1936-1932=4>>4 years
Then double the age gap to find how many years passed between the sister's birth and the grandmother's: 4 years * 2 = <<4*2=8>>8 years
Then add 8 years to the older sister's birth year to find the grandmother's birth year: 1936 + 8 = <<1936+8=1944>>1944
#### 1944

Answer the following multiple choice question by selecting the correct option.
Context: Proteins Function as Enzymes If you were trying to type a paper, and every time you hit a key on your laptop there was a delay of six or seven minutes before you got a response, you would probably get a new laptop. In a similar way, without enzymes to catalyze chemical reactions, the human body would be nonfunctional. It functions only because enzymes function. Enzymatic reactions—chemical reactions catalyzed by enzymes—begin when substrates bind to the enzyme. A substrate is a reactant in an enzymatic reaction. This occurs on regions of the enzyme known as active sites (Figure 2.27). Any given enzyme catalyzes just one type of chemical reaction. This characteristic, called specificity, is due to the fact that a substrate with a particular shape and electrical charge can bind only to an active site corresponding to that substrate.

Question: Ajay and Vijay have some marbles with them. Ajay told Vijay "if you give me 'x' marbles, both of us will have equal number of marbles". Vijay then told Ajay "if you give me twice as many marbles, I will have 30 more marbles than you would". Find 'x'?
A: 7
B: 5
C: 6
D: 4
Answer:

Answer the following multiple choice question by selecting the correct option.
Context: If Vijay gives 'x' marbles to Ajay then Vijay and Ajay would have V - x and A + x marbles.
V - x = A + x --- (1)
If Ajay gives 2x marbles to Vijay then Ajay and Vijay would have A - 2x and V + 2x marbles.
V + 2x - (A - 2x) = 30 => V - A + 4x = 30 --- (2)
From (1) we have V - A = 2x
Substituting V - A = 2x in (2)
6x = 30 => x = 5.

Answer the following multiple choice question by selecting the correct option.
Context: Genes that are located on the same chromosome are called linked genes . Alleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-over occurs when two homologous chromosomes exchange genetic material during meiosis I. The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over. At the following link, you can watch an animation showing how genes on the same chromosome may be separated by crossing-over: http://www. biostudio. com/d_%20Meiotic%20Recombination%20Between%20Linked%20Genes. htm .

Answer the following multiple choice question by selecting the correct option.
Context: Let the four integers be A, B, C and D where A > B > C > D.
(A + B + C + D)/4 = 69 => A + B + C + D = 276 ---> (1)
A = 93, D = 39 and B - C = 22
(1) => B + C = 276 - (A + D) = 276 - 132 = 144.
B + B -22 = 144
B = (144 + 22)/2 = 83

Question: What kinds of waves are composed of various oscillating electric and magnetic fields?
A: elastic
B: tidal
C: electromagnetic
D: seismic
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Figure 27.45 illustrates how the component of the electric field parallel to the long molecules is absorbed. An electromagnetic wave is composed of oscillating electric and magnetic fields. The electric field is strong compared with the magnetic field and is more effective in exerting force on charges in the molecules. The most affected charged particles are the electrons in the molecules, since electron masses are small. If the electron is forced to oscillate, it can absorb energy from the EM wave. This reduces the fields in the wave and, hence, reduces its intensity. In long molecules, electrons can more easily oscillate parallel to the molecule than in the perpendicular direction. The electrons are bound to the molecule and are more restricted in their movement perpendicular to the molecule. Thus, the electrons can absorb EM waves that have a component of their electric field parallel to the molecule. The electrons are much less responsive to electric fields perpendicular to the molecule and will allow those fields to pass. Thus the axis of the polarizing filter is perpendicular to the length of the molecule.

Question: Porter earns $8 per day and works 5 times a week. His manager is asking him to work an extra day that promises him an extra fifty percent on top of his daily rate. How much money will he earn after a month if he renders overtime every week?
A: 166.4
B: 209
C: 208
D: 416
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Porter's weekly earning is $8x5 = $<<8*5=40>>40.
Porter's monthly earning is $40x4= $<<40*4=160>>160.
The extra amount he will earn when he works on his overtime is $8 x 50/100 = $<<8*50/100=4>>4.
So the amount he will earn on his overtime is $8 + $4 = $<<8+4=12>>12.
Since he will render overtime once every week, the total overtime pay he will earn in a month is $12 x 4 = $<<12*4=48>>48.
Therefore the total money he will earn in a week is $160+$48 = $<<160+48=208>>208.

It lies below the lowest altitude a spacecraft can orbit. Maybe that's just as well. If you were in the mesosphere without a space suit, your blood would boil! This is because the pressure is so low that liquids would boil at normal body temperature.

Question: What is the sum of all remainders obtained when the first 110 natural numbers are divided by 9?
A: 397
B: 401
C: 403
D: 405
Answer:

Answer the following multiple choice question by selecting the correct option.
Context: A positive integer can give only the following 9 remainders when divided by 9: 1, 2, 3, 4, 5, 6, 7, 8, and 0.
1 divided by 9 gives the remainder of 1;
2 divided by 9 gives the remainder of 2;
...
8 divided by 9 gives the remainder of 8;
9 divided by 9 gives the remainder of 0.
We'll have 11 such blocks, since 99/9=11. The last will be:
91 divided by 9 gives the remainder of 1;
92 divided by 9 gives the remainder of 2;
...
98 divided by 9 gives the remainder of 8;
99 divided by 9 gives the remainder of 0.
The last number, 100, gives the remainder of 1 when divided by 9, thus the sum of all remainders will be:
11(1+2+3+4+5+6+7+8+0)+1=403.

Answer:

Answer the following multiple choice question by selecting the correct option.
Context: In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern. In a human karyotype, autosomes or “body chromosomes” (all of the non–sex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). The X and Y chromosomes are not autosomes. However, chromosome 21 is actually shorter than chromosome 22. This was discovered after the naming of Down syndrome as trisomy 21, reflecting how this disease results from possessing one extra chromosome 21 (three total). Not wanting to change the name of this important disease, chromosome 21 retained its numbering, despite describing the shortest set of chromosomes. The chromosome “arms” projecting from either end of the centromere may be designated as short or long, depending on their relative lengths. The short arm is abbreviated p (for “petite”), whereas the long arm is abbreviated q (because it follows “p” alphabetically). Each arm is further subdivided and denoted by a number. Using this naming system, locations on chromosomes can be described consistently in the scientific literature.

Question: Big Dig Mining Company mines three different types of ore: copper, iron, and nickel. Across all their mines, 10% of their output is nickel, 60% is iron, and the rest is copper. They mine 720 tons of nickel a day. How many tons of copper does Big Dig Mining Company mine daily?
A: 360
B: 540
C: 180
D: 288
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Let R be the total ore output of the company.
Of Big Dig’s output, 100 - 10 - 60 = <<100-10-60=30>>30% is nickel.
Since 720 is 60% of 100% of their output, 720 / R = 60 / 100.
Thus, Big Dig mines R = 100 * 720 / 60 = <<100*720/60=1200>>1200 tons of ore daily.
Therefore, Big Dig mines 1200 * 30 / 100 = <<1200*30/100=360>>360 tons of copper daily.

Question: Ramu rides his bike at an average speed of 45 km/hr and reaches his desitination in four hours. Somu covers the same distance in six hours. If Ramu covered his journey at an average speed which was 9 km/hr less and Somu covered his journey at an average speed which was 10 km/hr more, then the difference in their times taken to reach the destination would be (in minutes).
A: 23 minutes
B: 30 minutes
C: 87 minutes
D: 16 minutes
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Distance travelled by Ramu = 45 * 4 = 180 km
Somu travelled the same distance in 6 hours.
His speed = 180/6 = 30 km/hr
Hence in the conditional case, Ramu's speed = 45 - 9 = 36 km/hr and Somu's speed = 30 + 10 = 40km/hr.
Therefore travel time of Ramu and Somu would be 5 hours and 4.5 hours respectively. Hence difference in the time taken = 0.5 hours = 30 minutes.
Answer: B

Answer the following multiple choice question by selecting the correct option.
Context: Each organism has the ability to survive in a specific environment. Dry desert environments are difficult to live in. Desert plants have special stems and leaves to conserve water. Animals have other ways to live in the desert. The Namib Desert receives only 1.5 inches of rainfall each year. The Namib Desert beetle lives there. How do the beetles get enough water to survive? Early morning fog deposits water droplets. The droplets collect on a beetle's wings and back. The beetle tilts its rear end up. When the droplet is heavy enough, it slides forward. It lands in the beetle’s mouth. There are many other environments that need unique approaches for survival ( Figure below ).

A: 0
B: 9
C: 8
D: 7
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: The digit sum of 44444444 is when remainder obtained 44444444 divided by 9
44444444 = (45−1)44(45−1)44
Each term is a multiple of 9 but the last term which is (−1)44(−1)44 = 1
So the digit sum of 44444444 is 1.
Now the divisibility rule for 3, 9, 27... is the sum of the digits should be divisible by 3, 9, 27 respectively. In each case the digit sum is either multiple of 3 or 9.
So for any value of n > 1, the given expression is not divisible by 3n
