Question

the cost price of 36 books is equal to the selling price of 30 books gain percent is​

Answer 1

Let the C.P. of 1 book be 1

C.P. of 36 books = 36

S.P. of 30 books = C.p. of 36 books

= 36

For 30 books,

C.P. = 30

S.P. = 36

Profit = S.p - C.P.

= 36 -30

= 6

Profit % = Profit / C.P. * 100

= 6/36*100

$6 \div 36 \times 100$

Ans = 16.66%
