Question

The cost price of 8 books is equal to the selling price of 6 books. Find the gain percent

Answer 1

Let the cost price of 1 book be Re.1.

Cost price of 6 books = Rs.6
Selling price of 6 books = Rs.8

Gain = (SP - CP)
Gain = (8 - 6)
= Rs.2

Gain% = (Gain/CP∗100)%
= (2/6∗100)%
= 33.3% Ans.

Ans.) The gain is 33.3%.

Answer 2

Given - The cost price of 8 books is equal to the selling price of 6 books

Find - Profit percentage

Solution - Profit percentage is 33.3%

Let the CP of 8 books be x

CP of 1 book = x/8

SP of 6 books = x

SP of 1 book = x/6

Profit = SP - CP

Profit = x/6 - x/8

Profit = 4x - 3x/24

Profit = x/24

Profit percentage = Profit/CP*100

Profit percentage = (x/24)/(x/8)*100

Profit percentage = 8x*100/24x

Profit percentage = 100/3

Profit percentage = 33.3%

So, the profit percentage is 33.3%
