Answer 1

Step-by-step explanation:

Let the cost Price of the TV = Rs x

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

5

6x

∵ Gain = Selling price - Cost price

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

5

6x

−x

= \frac{(6x - 5x)}{5}

5

(6x−5x)

= \frac{x}{5}

5

x

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

CP

(g×100)

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

x

x

×100

= 20%
