Question

Buy a book at Tk 50 and sell it at 55 rupees to determine the profit loss

Answer 1

C.P.=50 rs
S.P.=55 rs

As C.P. is less than S.P. , profit has been there.

Profit=55-50=5 rs
Profit percent=
profit÷c.p. x 100
=5/50 x 100=10%

Answer 2

1 tk =0.86 rs

50 tk =43rs

so there is a loss of 12 rupees in selling the book at 55rs

and loss %= 24 %
