60 kg of salt water contains 5% salt. How much water must evaporate so that the salt becomes 8% of the solution?
सही उत्तर: क) 22.5 kg
Salt = 3 kg; at 8% the solution must weigh 3/0.08 = 37.5 kg, so 60 − 37.5 = 22.5 kg must evaporate.

A man rowing upstream drops his hat into the river and notices it 10 minutes later. He turns back immediately and, rowing at the same speed relative to the water, catches the hat 1 km downstream from where it fell. What is the speed of the stream?
सही उत्तर: घ) 3 km/h
Relative to the water he rows away 10 min and back 10 min, so the hat drifts 1 km in 20 minutes: speed = 3 km/h.

Two runners start together from the same point on a 400 m circular track and run in opposite directions at 6 m/s and 4 m/s. How many times do they meet in the first 10 minutes?
सही उत्तर: ख) 15 times
They close 10 m every second, so they meet every 400/10 = 40 s; in 600 s that is 600/40 = 15 meetings.

A car covers 300 km at a uniform speed. If its speed were 10 km/h less, the journey would take 1 hour more. What is its speed?
सही उत्तर: ग) 60 km/h
300/(s − 10) − 300/s = 1 gives s² − 10s − 3,000 = 0, so s = 60 (check: 6 h vs 5 h).
