Correct Answer: Ans.16$\frac{2}{3}$%

Explanation:

At 25% profitIf cost price is Tk 100, then selling price would be 125 Tk.

If selling price is 125 tk. then cost price would be = 100 Tk

If selling price is 4000 tk. then cost price would be = $\frac{100×4000}{125}$ = 3,200 Tk.

Total cost price of two commodities = 4,000 + 4,000 = 8,000 Tk.

Then the cost price of another commodity = 8,000 -3,200 = 4,800 Tk.

But the sold another commodities = 4,000 Tk

So he loses = 4,800 — 4,000 = 800 Tk.

Loss % = $\frac{800}{4800}\times 100$ = $\frac{2}{3}$%
