Correct Answer: Option C
Explanation

200 mangoes at 4 for N2.50

\(\implies\) Total cost price = \(\frac{200}{4} \times N 2.50\)

= N 125.00

Since 30 mangoes got spoilt \(\implies\) Left over = 200 - 30

= 170 mangoes 

170 mangoes at 2 for N 2.40

\(\implies\) Total selling point = \(\frac{170}{2} \times N 2.40\)

= N 204.00

Profit : N (204.00 - 125.00) = N 79.00

% profit = \(\frac{79}{125} \times 100%\)

= 63.2% profit.
