Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is? | [
"3 : 2",
"1 : 3",
"4 : 3",
"3 : 4"
] | A | Explanation:
Let the speeds of the two trains be x m/sec and y m/sec respectively.
Then, length of the first train = 27x metres,
and length of the second train = 17y metres.
( 27x + 17y ) / (x+ y )= 23
=> 27x + 17y = 23x + 23y
=> 4x = 6y
=> ( x/y ) = ( 3/2 )

Worker A takes 8 hours to do a job. Worker B takes 10 hours to do the same Job.How long should it take both A and B, working together but independently, to do the same job? | [
"45/7 days",
"15/4 days",
"40/3 days",
"40/9 days"
] | D | A’s 1 hour's work = 1/8
B's 1 hour's work = 1/10
(A + B)'s 1 hour's work = (1/8) +(1/10)=9/40
Both A and B will finish the work in 40/9 days

A train 100 m long is running at the speed of 30 km/hr. Find the time taken by it to pass a man standing near the railway line. | [
"16 sec.",
"12 sec.",
"10 sec.",
"14 sec."
] | B | Solution
Speed of the train = (30 x 5/18)m/sec
= (25 / 3) m/sec.
Distance moved in passing
the standing man = 100 m.
Required time taken = 100 /( 25 / 3)
=(100 x 3 / 25) sec
= 12 sec.

"6%",
"4%",
"14%",

A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform? | [
"120 m",
"240 m",
"120 m",
"None of these"
] | B | Speed = 54 x 5/18 m/sec = 15 m/sec.
Length of the train = (15 x 20)m = 300 m.Let the length of the platform be x metres.
Then, 9x + 3000/36 = 15
x + 300 = 540
x = 240 m. Answer: Option B | AquaRat_train |
