Best answer

Answer: A. 15.2%

Answer: (A) 15.2%

Take 6 oranges of each kind (LCM of 3 and 2). Cost = 2 × 5 + 3 × 5 = ₹25 for 12 oranges.

SP of 12 oranges = 12 × \(\frac{12}{5}\) = ₹28.80.

Profit% = \(\frac{3.80}{25} \times 100 = 15.2\%\).

Trap: averaging the rates as "5 oranges for ₹10" (₹2 each) gives 20%; the costs per orange must be averaged, not the counts.
