Correct Answer: 12 %

Explanation:

Let, the trader bought x dozens of mangoes & x dozens of apples.

1 dozen mango costs = 150 Tk.

1: dozen mango costs = 150x Tk.

1 dozen apple costs = 100 Tk.

x dozen apple costs = 100x Tk.

(x + x) = 2x dozens fruits cost (150x + 100x) = 250x Tk.

Again, Selling price 1 dozen of fruits = 140 Tk.

Selling price 2:: dozen of fruits = 2x x 140 = 280x Tk.

Profit percentage = $\frac{30x\cdot100}{250x}$ = 12%.
