Correct Answer: The statement of this problem is not correct.

Explanation:

Let, the number of apple = x

The number pears = 21 -x

Total price of apple = Tk. 10x

And total price of pears = Tk. (21 — x)15

=>10x+15(21—x)=380

=>10x+315-15x=380

=>—5x=380—315

=>—5x=65

x = — 13, the negative number is not possible.(problem is not correct.)
