Question

If the selling price of a TV set is equal to 6/5 of its cost price, find the gain percent .

Answer 1

.this is right i think so

Answer 2

Solution :

Let the cost Price of the TV = Rs x

Selling price = $\frac{6x}{5}$

∵ Gain = Selling price - Cost price

Gain = $\frac{6x}{5} - x$

        =  $\frac{(6x - 5x)}{5}$

        = $\frac{x}{5}$

Gain percent = $\frac{(g \times 100)}{CP}$

                      = $\frac{\frac{x}{5} \times 100}{x}$

                      = 20%
