Vikas sells two watches. The cost price of the first watch is equal to the selling price of the second watch. The first watch is sold at a profit of 20 percent and the second watch is sold at a loss of 10 percent. What is the ratio of the selling price of the first watch to the cost price of the second watch? Correct Answer 27 : 25

Given:

Cost price(CP) of 1st watch = Selling price(SP) of 2nd watch

Profit on 1st watch = 20%

Loss on 2nd watch = 10%

Formula used:

SP = CP + Profit

SP = CP - Loss

Loss% = (Loss/CP) × 100

Profit% = (Profit/CP) × 100

Calculation:

Let the CP of 1st watch = x = SP of 2nd watch

SP of 1st watch = 1.2x

Let the CP of 2nd watch = y

⇒ 0.9y = x

⇒ y = x/0.9

Ratio of SP of 1st watch to the CP of 2nd watch =  x : y

⇒ x : y = 1.2x : x/0.9

⇒ x : y = 27 : 25

∴ The ratio of the selling price of the first watch to the cost price of the second watch = 27 : 25
