Two full tanks, one shaped like a cylinder and the other like a cone, contain jet fuel. The cylindrical tank holds 500 L more than the conical tank. After 200 L of fuel has been pumped out from each tank, the cylindrical tank contains twice the amount of fuel in the conical tank. How many litres of fuel did the cylindrical tank have when it was full?
-
- 700 L
- 1,000 L
- 1,100 L
- 1,200 L
- 700 L
Correct Option: D
Let conical tank contain ‘q’ litres of fuel, then cylindrical tank would hold (q + 500) litres.
So, (q – 200)2 = q + 500 – 200
⇒ 2q – 400 = q + 300
⇒ 2q - q = 400 + 300
⇒ q = 700
Hence, cylindrical tank would hold 700 + 500 = 1200 L
