Two full tanks one shaped like the cylinder and the other like a cone contain liquid fuel the cylindrical tank held 500 lts more then the conolical tank After 200 lts of fuel is pumped out from each tank the cylindrical tank now contains twice the amount of fuel in the canonical tank How many lts of fuel did the cylindrical tank have when it was full?

Consider the cylindrical tank capacity x + 500 then the conical tank capacity = x


After 200 lts pumped out, then remaining fuel with the tanks = x +300, x - 200


It is provided that first term is doubt the second.

x+300x−200=21

Therefore,

x+300 = 2x-400


Therefore,


x = 700


total amount of fuel in cylindrical tank=(500+700)=1200 lit

Cylindrical tank capacity = 1200 lts.
