A train passes a station platform in 34 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? | [
"240",
"210",
"200",
"260"
] | B | Speed = [54 * 5/18] m/sec = 15 m/sec.
Length of the train = (15 * 20) m = 300 m.
Let the length of the platform be x meters.
Then, x + 300 / 34 = 15
x + 300 = 510
x = 210 m.

In a regular week, there are 5 working days and for each day, the working hours are 8. A man gets Rs. 2.40 per hour for regular work and Rs. 3.20 per hours for overtime. If he earns Rs. 432 in 4 weeks, then how many hours does he work for ? | [
"175",
"575",
"475",
"275"
] | A | Suppose the man works overtime for x hours.
Now, working hours in 4 weeks = (5 x 8 x 4) = 160.
160 x 2.40 + x x 3.20 = 432
3.20x = 432 - 384 = 48
x = 15.
Hence, total hours of work = (160 + 15) = 175.

A and B undertake to do a piece of work for Rs 600. A alone can do it in 6 days while B alone can do it in 8 days. With the help of C, they can finish it in 3 days, Find the share of each? | [
"400, 300, 100",
"300, 225, 75",
"None of these",
"200, 225, 80"
] | B | C’s one day’s work = (1/3) - (1/6 + 1/8) = 1/24
Therefore, A : B : C = Ratio of their one day’s work = 1/6 : 1/8 : 1/24 = 4 : 3 : 1.
A’s share = Rs (600 x 4/8) = 300
B’s share = Rs (600 x 3/8) = 225
C’s share = Rs[600 - (300 + 225)] = Rs 75
