Question

A sells his goods 30% cheaper than b and 30% dearer than

c. by what percentage is the cost of c's goods cheaper than b's goods.

Answer 1

Solution:

Let B be the 100%.

Also, A sell 30% cheaper than C = 70

Since 130% selling price of goods by C = 70

C = (100*70)/30

= 53.85

C is cheaper than B = 100 - 53.85 = 46.15

Changing in percentage is 46.15%.
