Heating plant

Workers dump imported coke at heating plant. On the first day used half of the amount, the second day three quarters the rest and on the third day left 120 tons.

How much coke they dump at heating plant?

Correct result:

x =  960 t

Solution:


x-1/2 x - 3/4 • (x-1/2 x) = 120

x-1/2•x - 3/4 • (x-1/2•x) = 120

0.5x = 480

x = 960
