Question

Example 5. Rajiv sold an article for Rs.56 which cost him Rs. X. If he gained x% on his outlay, what was his cost​

Answer 1

Answer:

Selling price (s.p ) = 56 Rs.

cost price ( c.p ) = x Rs.

gain = x%

i.e., profit = x/100

w.k.t.

Profit = S.P - C.P

x/100 = 56 - x

x/100 + x = 56

x (1/100 + 1 ) = 56

x ( 101/100 ) = 56

x = 56 × 100/101

x = 5600 / 101

x = 55.44 Rs.
