Question

He c.P of 15 books is equal to the s.P of 18 books. Find his gain% or loss%?

Answer 1

Solution:
Since CP of 15 books = SP of 18 books

Let us assume that the cost of 1 book is ₹1
Therefore, cost of 18 books is ₹18, but he sold at ₹15

Therefore, Loss = 18-15 = ₹3
& Loss% = (3/18)*100 = 16.67%

Hence, Loss is 16.67%
