Answer the following multiple choice question by selecting the correct option.
Question: Timothy has $50 to spend at a souvenir shop. He sees some t-shirts that cost $8 each, key chains that sell 3 pieces for $2, and bags that cost $10 each. Timothy buys 2 t-shirts and 2 bags. How many pieces of key chains can he buy with the amount of money he has left?
A: 21
B: 22
C: 20
D: 31.5
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: The two t-shirts amount to $8 x 2 = $<<8*2=16>>16.
The two bags amount to $10 x 2= $<<10*2=20>>20.
So Timothy spent $16 + $20 = $<<16+20=36>>36 for the shirts and bags.
He still has $50 - $36 = $<<50-36=14>>14 left to spend for the key chains.
With the money, he can buy $14/$2 = <<14/2=7>>7 sets of key chains.
Therefore, he can buy 7 x 3 = <<7*3=21>>21 pieces of key chains.

A: habitats
B: food
C: genome
D: enemies
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: DNA technology has proved very beneficial to humans. Transgenic animals are animals that have incorporated a gene from another species into their genome. They are used as experimental models to perform phenotypic tests with genes whose function is unknown, or to generate animals that are susceptible to certain compounds or stresses for testing purposes. Other applications include the production of human hormones, such as insulin. Many times these animals are rodents, such as mice, or fruit flies ( Drosophila melanogaster ). Fruit flies are extremely useful as genetic models to study the effects of genetic changes on development. GloFish are the first genetically modified animal to be sold as a pet and are transgenic zebrafish transfected with a natural fluorescence gene.

Answer the following multiple choice question by selecting the correct option.
Context: The laboratory spent 2 / 3 * 150 = 300 / 3 = $<<2/3*150=100>>100 on test tubes.
They spent a further 100 / 2 = $<<100/2=50>>50 on safety gear.
In all, they spent 150 + 100 + 50 = $<<150+100+50=300>>300.
Thus, 325 - 300 = $<<325-300=25>>25 of the laboratory’s budget remained.

Answer:

Answer the following multiple choice question by selecting the correct option.
Context: ♦ Glasses are mixtures of oxides, the main component of which is silica (SiO2). Silica is called the glass former, while additives are referred to as glass modifiers. The crystalline lattice of the glass former breaks down during heating, producing the random atomic arrangements typical of a liquid. Adding a modifier and cooling the melt rapidly produces a glass. How does the three-dimensional structure of the glass differ from that of the crystalline glass former? Would you expect the melting point of a glass to be higher or lower than that of pure SiO2? Lead glass, a particular favorite of the Romans, was formed by adding lead oxide as the modifier.

He decided now to buy 2 CDs by "The Dark", 1 CD by the creator "AVN", and 5 CDs that are mixes of songs from the 90s. The price of the "AVN" CD is $12 and it is half the price of one CD by "The Dark". The 5 CDs of 90s music cost is 40% of all the cost of all other CDs Alan is going to buy. How much will Alan have to pay for all the products?
A: 126
B: 74
C: 84
D: 85
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: If one "AVN" is half the price of one "The Dark" CD, that means one CD of "The Dark" costs 12 * 2 = $<<12*2=24>>24.
So for two "The Dark" CDs, Alan needs to pay 24 * 2 = $<<24*2=48>>48.
So all CDs cost by now 12 + 48 = $<<12+48=60>>60.
The 90s music CDs cost 40/100 * 60 = $<<40/100*60=24>>24.
That means for all CDs Alan needs to pay 60 + 24 = $<<60+24=84>>84.

In 4 weeks all the chickens lay 168 * 4 = <<168*4=672>>672 eggs
672 eggs equal 672 / 12 = <<672/12=56>>56 dozens.
Kelly would make 56 * 5 = <<56*5=280>>280 dollars

Question: When a balloon is rubbed against hair, they attract each other because of a difference in what?
A: charges
B: Force
C: Friction
D: actions
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Did you ever rub an inflated balloon against your hair? You can see what happens in Figure below . Friction between the rubber of the balloon and the baby’s hair results in electrons from the hair "rubbing off" onto the balloon. That’s because rubber attracts electrons more strongly than hair does. After the transfer of electrons, the balloon becomes negatively charged and the hair becomes positively charged. As a result, the individual hairs repel each other and the balloon and the hair attract each other. Electrons are transferred in this way whenever there is friction between materials that differ in their ability to give up or accept electrons.

Question: If the compound interest on a certain sum for 2 years at 12% p.a. is Rs.1590, What would be the simple interest for same rate and same period?
A: Rs.1500
B: Rs.1450
C: Rs.1550
D: Rs.1650
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Let principal be P.
Then Amount = P + 1590
According to formula, Amount = P*[1 + 0.12]^2
Hence, we get, P+ 1590 = P*[1.12]^2
So, P + 1590 = 1.2544P
So, 0.2544P = 1590
So, P = 6250
Hence, simple interest on �6250 @ 12% for 2 years = 6250*12/100*2 = 1500

Answer the following multiple choice question by selecting the correct option.
Context: The deadly nerve gas Sarin irreversibly inhibits acetycholinesterase. What effect would Sarin have on muscle contraction? After depolarization, the membrane returns to its resting state. This is called repolarization, during which voltagegated sodium channels close. Potassium channels continue at 90% conductance. Because the plasma membrane sodium–potassium ATPase always transports ions, the resting state (negatively charged inside relative to the outside) is restored. The period immediately following the transmission of an impulse in a nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse, is called the refractory period. During the refractory period, the membrane cannot generate another action potential. The refractory period allows the voltage-sensitive ion channels to return to their resting configurations. The sodium potassium ATPase continually moves Na+ back out of the cell and K+ back into the cell, and the K+ leaks out leaving negative charge behind. Very quickly, the membrane repolarizes, so that it can again be depolarized.

Answer the following multiple choice question by selecting the correct option.
Context: Reporting Scientific Work Whether scientific research is basic science or applied science, scientists must share their findings for other researchers to expand and build upon their discoveries. Communication and collaboration within and between sub disciplines of science are key to the advancement of knowledge in science. For this reason, an important aspect of a scientist’s work is disseminating results and communicating with peers. Scientists can share results by presenting them at a scientific meeting or conference, but this approach can reach only the limited few who are present. Instead, most scientists present their results in peer-reviewed articles that are published in scientific journals. Peer-reviewed articles are scientific papers that are reviewed, usually anonymously by a scientist’s colleagues, or peers. These colleagues are qualified individuals, often experts in the same research area, who judge whether or not the scientist’s work is suitable for publication. The process of peer review helps to ensure that the research described in a scientific paper or grant proposal is original, significant, logical, and thorough. Grant proposals, which are requests for research funding, are also subject to peer review. Scientists publish their work so other scientists can reproduce their experiments under similar or different conditions to expand on the findings. The experimental results must be consistent with the findings of other scientists. There are many journals and the popular press that do not use a peer-review system. A large number of online openaccess journals, journals with articles available without cost, are now available many of which use rigorous peer-review systems, but some of which do not. Results of any studies published in these forums without peer review are not reliable and should not form the basis for other scientific work. In one exception, journals may allow a researcher to cite a personal communication from another researcher about unpublished results with the cited author’s permission.

A: 223
B: 175
C: 297
D: 267
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Explanation:
Suppose the man works overtime for x hours.
Now, working hours in 4 weeks = (5 x 8 x 4) = 160.
{\color{Blue} \therefore } 160 x 2.40 + x x 3.20 = 432
=> 3.20x = 432 - 384 = 48
=> x = 15.
Hence, total hours of work = (160 + 15) = 175.
Answer: B) 175

Answer the following multiple choice question by selecting the correct option.
Context: Explanation :
We try to get an upper bound on the value of w.
After taking a look at the options we figure it out that if we take v=-1,z=-2 and u=-0.5.
we get the lower bound as -4.
If we take v=1, z=-2 and u=-0.5 we have the upper bound as 4.
Hence, the right option is 2.ie -4 ≤ w ≤ 4
Answer : B
