A boat whose speed in still water is 15 km/h takes 1 hour longer to go 36 km upstream than to go 36 km downstream. What is the speed of the stream?
सही उत्तर: ख) 3 km/h
36/(15 − s) − 36/(15 + s) = 1 gives s² + 72s − 225 = 0, so s = 3 km/h (check: 3 h − 2 h = 1 h).

Station P and station Q are 330 km apart. A train leaves P at 7 a.m. for Q at 60 km/h, and another leaves Q at 8 a.m. for P at 75 km/h. At what time do they meet?
सही उत्तर: घ) 10 a.m.
By 8 a.m. the first train covers 60 km; the remaining 270 km closes at 135 km/h in 2 hours, so they meet at 10 a.m.

A train passes a man standing on a platform in 18 seconds and passes the 300 m long platform in 30 seconds. What is the length of the train?
सही उत्तर: ग) 450 m
The extra 300 m takes 12 s, so speed = 25 m/s; length = 25 × 18 = 450 m.

12 men working 8 hours a day dig a 480 m long trench in 10 days. How many men working 6 hours a day are needed to dig a 720 m trench in 12 days?
सही उत्तर: क) 20
Men = 12 × (8/6) × (10/12) × (720/480) = 12 × 4/3 × 5/6 × 3/2 = 20.

A completes 60% of a job in 15 days and then B joins him; together they finish the rest in 4 days. In how many days can B alone do the whole job?
सही उत्तर: घ) 16 2/3 days
A does 4% per day; together they do 40%/4 = 10% per day, so B does 6% per day and needs 100/6 = 16 2/3 days.

Two inlet pipes fill a tank in 20 minutes and 30 minutes. With an outlet pipe also open, the empty tank fills in 24 minutes. How long would the outlet alone take to empty the full tank?
सही उत्तर: ग) 24 minutes
1/20 + 1/30 − 1/x = 1/24, i.e. 1/12 − 1/x = 1/24, so 1/x = 1/24.

2 men and 3 women can finish a job in 10 days, while 3 men and 2 women can finish it in 8 days. In how many days can 2 men and 1 woman finish it?
सही उत्तर: ख) 12.5 days
Solving gives one man's daily work 7/200 and one woman's 1/100, so 2 men + 1 woman do 16/200 = 2/25 per day: 12.5 days.

A can do a job in 20 days and B in 30 days. They work on alternate days, A starting on the first day. In how many days will the job be finished?
सही उत्तर: ख) 24 days
Every two days they finish 1/20 + 1/30 = 1/12; after 22 days 11/12 is done, A adds 1/20 on day 23 and B the last 1/30 on day 24.
