Correct Answer: TK 200
Explanation:
Let, the cost price he = 100 Tk.
At 20% loss, selling price will be = (100 — 20) = 80 Tie
And at a 10% profit, the selling price would be = (100 + 10) = 110 Tk.
Difference between selling price = (110 — 80) = 30 Tk.
If he sold at 30 Tk. more then cost price = 100 Tk.
If he sold at 60 Tk. more then cost price = Tk. $\frac{100 \cdot 60}{30}$= Tk. 200
