Question

the cost price of 8 books is equal to the selling price of 6 books find the gain percentage​

Answer 1

Answer:

the cp of 8 books us equal to the sp of 6 books . the gain percentage is 25%

Answer 2

Answer:

The Gain Percentage is 33.33%

Now here is a Step-by-step explanation:

Let us assume the C.P of 8 books as 100

C.P of 1 book is 100/8

∴ C.P of 1 book is 12.5

If the C.P of 1 book is 12.5

The C.P of 6 books is 12.5 X 6

C.P of 6 books is 75

But as the Question States, the C.P of 8 books is S.P of 6 Books

So the C.P of 8 books = 100

S.P of 6 books = 100

but assuming the C.P of 1 book is 12.5 the C.P of 6 books is 75

∴ Gain % = (100 - 75) / 75 X 100

∴ Gain % = 25 / 75 X 100

= 33.33

∴ Gain % = 33.33
