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
