Question

A book seller buys 200 books for 12000 rupees. He wants to sell those on a profit so that he gets 20 books free of cost. By what percent profit he should sell books?​

Answer 1

Answer:

$\huge\underline\bold {Answer:}$

C.P. of 200 textbooks = 12000 rupees.

Profit = C.P. of 20 textbooks

Therefore, S.P. of 200 textbooks

= C.P. of 200 textbooks + C.P of 20 textbooks

= C.P. of 220 textbooks.

C.P. of 1 textbooks = 12000/200 = 60 rupees.

Therefore, S.P. of 200 textbooks

= 220 × 60

= 13200 rupees

Therefore, profit per cent

= {(13200 – 12000) ÷ 12000} × 100

= {1200/12000} × 100

= 10%
