Water flows into a tank 100 m x 150 m x 2 m through a rectangular pipe 1.5 m x 1.25 m at a speed of 20 km/h. In what time, will the water rise by 2 m ?

1. 96 min
2. 50 min
3. 48 min
4. 75 min

Correct Option: C

Volume of water in the tank = 100 x 500 x 2 = 30000 m³
Speed of water = 20 x 1000/60 = 1000/3 m/min
water flow per minute = (15/10) x (125/100) x (1000/3) = 625 m³
Time taken = 30000/625 = 48 min
