B. 45,000 litres
C. 4,500 litres
D. 900 litres
E. None of these
Solution(By Examveda Team)
Volume of the tank = length * beadth * Depth = 15 *6 *10 = 900 cubic meter.
1 cubic meter = 1000 liter.
So, 900 cubic meter = 900 *1000 = 900000 liter.
Total Capacity of the tank = 900000 liter.
Water Drawn = 1000 liter.
