The volume of rain water in the land which could have been collected and the volume of water in the tank should be equal . Let, level of water in the tank is h meter. According to the question, ⇒ 3/100 × 2000 × 2000 × 210/300 = 200 × 10 × h ⇒ h = 42 m Volume of water in the tank = 200m × 10m × 42m = 84000 m3 Since, water in the tank is 60% of its capacity. So, capacity of tank = (84000/60) × 100 = 140000 m3
