Option D:

Jamb Maths Solution: 

$\begin{align}  & \text{Cost of the mangoes }=\frac{200}{4}\times N2.50=N62.50 \\ & \text{30 got spoilt, so Tade had to sell 70 oranges} \\ & \text{He sold 2 for N2}\text{.40} \\ & \text{The total selling price }=\frac{70}{2}\times N2.40=N84 \\ & \text{Profit}=N84-N62.50=N21.5 \\ & \text{percent profit }=\frac{\text{profit}}{\text{cost price}}\times 100 \\ & \text{percent profit}=\frac{21.5}{62.50}\times 100=34.4 \\\end{align}$
