Question

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

Answer 1

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%

Answer 2

Greetings..!

Let Cost price = Rs x

Then,S.P = Rs 6x/5

Then gain = sp - cp = Rs x/5

So, gain percent = gain/cp *100 = ( x/5)*(1/x)*100 = 20%

Answer : Hence, gain percent = 20%
