Question

if the selling price of a tv set is equal to 6/5 pf its cost. find the gain per cent

Answer 1

Hi ,

Let the cost Price of the TV = Rs x

Selling price (s.p ) = 6x/5

Gain ( g ) = s.p - c.p

g = 6x/5 - x

= ( 6x - 5x ) /5

= x/5

Gain % = ( g × 100 )/CP

= ( x/5 × 100 ) / x

= 20%

I hope this helps you.

:)
