Question

If the cost price of 12 books is equal to
the selling price of 8 books, what is the
gain percent?​

Answer 1

Answer:

The gain percent is 50%

Step-by-step explanation:

Let the cost price of 1 book be Re.1

Cost price of 8 books = Rs.8

Cost price of 12 books = Rs.12

cost price of 12 books is equal to the selling price of 8 books

Sp of 8 books = CP of 12 books = Rs.12

CP of 8 books = Rs.8

SP>CP

the gain percent is 50%
