A 270 metres long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train? | [
"235 meter",
"225 meter",
"230 meter",
"None of these"
] | C | Explanation:
As trains are running in opposite directions so their relative speed will get added
So, Relative speed = 120 +80 = 200 kmph
= 200*(5/18) = 500/9 m/sec
Let the length of other train is x meter then
x+270 /9=500 /9
=>x+270=500
=>x=230
So the length of the train is 230 meters

If the salary of an employee is first increased by 20% and the decreased by 12%, then what is the change in his salary in percent? | [
"5.9 % increase",
"5.6 % increase",
"1.6 % increase",
"5.7 % increase"
] | B | Explanation:
Let the first change be denoted by ‘x’ and the second by ‘y’.
The net change is given by {x + y + (x*y)/100}%
Therefore, the net change in salary is {20 + (-12) + (20*(-12))/100}

A tyre has two punctures. The first puncture alone would have made the tyre flat in 8 minutes and the second alone would have done it in 6 minutes. If air leaks out at a constant rate, how long does it take both the punctures together to make it flat ? | [
"3 3/7min",
"3 2/5min",
"3 min",
"3 1/5min"
] | A | Explanation:
Do not be confused, Take this question same as that of work done question's. Like work done by 1st puncture in 1 minute and by second in 1 minute.
Lets Solve it:
1 minute work done by both the punctures =
(1/8+1/6)=(7/24)
So both punctures will make the type flat in
(24/7)mins=3 3/7mins

"C)109",
"B)103",
"A)113",
"D)101"

100 is not a prime number.
101 < 11 and 101 is not divisible by any of the prime numbers 2, 3, 5, 7, 11.
101 is a prime number.
Hence 101 is the smallest 3-digit prime number.
