Answer 2

Answer:

$\frac{2}{5} of \: the \: tanker \: is \: filled \: up \: |1 - \frac{2}{5} | or \: \frac{3}{5} of \: the \: tanker \: is \: empty \: . \\ \frac{3}{5} \: of \: the \: petrol \: tanker \: can \: hold \: 90 \: litres. \\ therefore \: a \: full \: tanker \: can \: hold \: 90 \times \frac{5}{3} \: or \: 150 \: litres$
