In what ratio must water be mixed with milk so that by selling the mixture at the cost price of milk, a milkman gains 20%?

Two runners start together from the same point on a 600 m circular track and run in the same direction at 4 m/s and 6 m/s. After how much time will they first meet again?
सही उत्तर: क) 5 minutes
Relative speed = 2 m/s; the faster must gain one full lap of 600 m, which takes 300 s = 5 minutes.

In a 1 km race, A beats B by 40 metres or by 8 seconds. How long does A take to finish the race?
सही उत्तर: घ) 192 seconds
B runs 40 m in 8 s, i.e. 5 m/s, so B takes 1000/5 = 200 s; A takes 200 − 8 = 192 seconds.

A boat's downstream speed is 14 km/h and the speed of the stream is 2 km/h. What is its upstream speed?
सही उत्तर: ग) 10 km/h
Speed in still water = 14 − 2 = 12 km/h; upstream speed = 12 − 2 = 10 km/h.

The speeds of A and B are in the ratio 3 : 4. A takes 30 minutes more than B to cover a certain distance. How long does A take?
सही उत्तर: ख) 2 hours
Times are in the ratio 4 : 3; the difference of 1 part = 30 minutes, so A takes 4 × 30 = 120 minutes = 2 hours.

Two trains of equal length take 10 seconds and 15 seconds respectively to pass a telegraph post. If they run in opposite directions, how long will they take to cross each other?
सही उत्तर: क) 12 seconds
Speeds are L/10 and L/15; time = 2L ÷ (L/10 + L/15) = 2 ÷ (1/6) = 12 seconds.

A train 240 m long crosses a bridge 360 m long in 36 seconds. What is the speed of the train?
सही उत्तर: घ) 60 km/h
Distance = 240 + 360 = 600 m; speed = 600/36 = 50/3 m/s = 50/3 × 18/5 = 60 km/h.

Two towns are 360 km apart. Two cars start at the same time from the two towns towards each other at 50 km/h and 70 km/h. After how long will they meet?
सही उत्तर: ग) 3 hours
Relative speed = 50 + 70 = 120 km/h; time = 360/120 = 3 hours.

A bus covers 300 km in 5 hours. By how much must its speed be increased to cover the same distance in 4 hours?
सही उत्तर: ख) 15 km/h
Present speed = 60 km/h; required = 300/4 = 75 km/h; increase = 15 km/h.
