Question

A drum contained 250 litres of oil . 5 % oil was lost due to leakage . how many litres of oil is still in the drum​

Answer 1

Oil Still remains in the Drum :-

$\sf = \frac{5}{100} \times 250 = \frac{1}{20} \times 250 = \frac{25}{2} = 12.5 \: liter \: \: \: was \: \: leaked$

so , Remaining = 250 - 12.5 = 237.5 liters
