Question

A tank holds 240 liters of fuel. How much fuel is the tank when it is 4/5 full? (Take π =²7)

A.7cm
B.14cm
C.22cm
D.28cm

Answer 1

C. 22cm

Explanation:

For the tank to be 4/5 full, it must have 240 liters * 4/5 = 192 liters of fuel in it.

So, there are 240 liters - 192 liters = 48 liters of remaining tank space = 48cm^3 at a rate of 240cm^3 per liter = 48 * 240/240cm^3 = 22cm.
