Question 66

The price of a cap is increased by 15%. If this results in a ₹27 increase in the price of the cap, then what is the increased price of the cap?

Solution

Let's assume the initial price of a cap is 100y.

The price of a cap is increased by 15%.

price of a cap after increase = 100y of (100+15)%

= 100y of 115%

= $$100y\times\frac{115}{100}$$

= 115y

If this results in a ₹27 increase in the price of the cap.

115y-100y = ₹27

15y = ₹27

y = $$\frac{27}{15}$$ = ₹1.8

price of a cap after increase = 115y

= $$115\times1.8$$

= ₹207
