is equal to : | [
"1",
"1/4",
"1/3",

Anup was asked to find the value of 7/12 of a sum of money Q. Instead of multiplying the same by 7/12,he divided it by 7/12 and his answer exceeded the correct answer by 95. The correct answer is: | [
"89",
"49",
"84",
"48"
] | B | Q=12/7*x-7/12*x=95 --> x=84 --> 7/12*x=49.

In a four numbers set, the second number is twice the first number, the first is one-third of the third and the third is 5 times the fourth. The average of the numbers is 24.75. The largest of these numbers is: | [
"25",
"35",
"None of these",
"9"
] | B | Explanation :
Let the fourth number be x.
Then, third number = 5x, first number = 5x/3
And second number = 10x/3
x + 5x + 10x/3 + 5x/3 = (33 x 4) or 11x = 132 or x = 12.
So, the numbers are 20, 40, 60 and 12.
Largest number = 60.

Two trains 85 m and 75 m long are running in same direction with speeds of 62 km/hr and 44 km/hr respectively. In what time will the first train cross the second train ? | [
"92 sec",
"13 sec",
"82 sec",
"32 sec"
] | D | Explanation:
Given that,
1st train speed = 62 km/hr
2nd train speed = 44 km/hr
Hence the relative speed of two trains is 62-44 = 18 km/hr m/s = 5 m/s.
There fore, the first train crosses the second train i.e (85+75)mts of distance with a speed of 5m/s in,
time = \frac{distance}{speed} \frac{(85+75)}{5} = 32 sec.
