Three business people who wish to invest in a new company. Each person is willing to pay one third of the total investment. . After careful calculation, they realize that each of them would pay $ 7500 less if they could find two more equal investors. How much is the total investment in the new business. | [
"d)\t$ 5,400",
"a)\t$ 64,000",
"c)\t$ 21,000",
"b)\t$ 56,250"
] | D | Initially each invest in x. Hence total investment is 3x.
Total investment is also 5(x-7500).
3x = 5(x-7500)
x= 5*7500/2 = 18750
3x = 56250 and the answer is B. | AquaRat_train |
A can do a work in 15 days and B in 20 days. If they work on it together for 4 days then the fraction of the work that is left is? | [
"9/13",
"7/15",
"8/15",
"1/10"
] | C | Explanation:
A’s one day work = 1/15
B’s one day work = 1/20
(A+B )’s one day work is = 1/15 +1/20 = 7/60
their 4 days work = 4 x 7/60 = 7/15
Remaining work = 8/15
Answer: Option D | AquaRat_train |
When 8 fair coins are tossed simultaneously, in how many outcomes will the first and the last coin turn up heads? | [
"64",
"31",
"3",
"1"
] | A | Total outcome is 2^8 = 256
Favourable cases = H_ _ _ _ _ _ H
The second to seventh places can be occupied by either H or T
There are 2^6 =64 ways that can be done.
Hence, the correct option is E | AquaRat_train |
John has 6 pairs of shoes; each pair is a different color. If Kim randomly selects 2 shoes without replacement from the 12 shoes, what is the probability that she will select 2 shoes of the same color? | [
"1/9",
"1/11",
"2/5",
"1/5"
] | B | Can be tackled in this way as well: Probability of selecting any 1 out of 12 shoes = 12/12 = 1
Probability of selecting the next shoe (out of 12 available) having the same color = 1/9 (as after selecting the 1st one, there is only 1 another shoe left with the same color).
Thus the total probability = 1*1/11=1/11.

A is faster than B. A and B each walk 24 km. The sum of their speeds is 7 km/hr and the sum of times taken by them is 14 hours. Then, A's speed is equal to? | [
"3 km/hr",
"17km/hr",
"19km/hr",
"16km/hr"
] | A | Let A's speed = x km/hr. Then, B's speed = (7 - x) km/ hr.
So, 24/x + 24/(7 - x) = 14
x2 - 98x + 168 = 0
(x - 3)(x - 4) = 0 => x = 3 or 4.
Since, A is faster than B, so A's speed = 4 km/hr and B's speed
= 3 km/hr.
