PROBLEM:
Chef sells a fruit for rupees X, and earns a profit of rupees Y.
If he increases the price of the fruit by 10\%, what’s his new profit?
EXPLANATION:
The new price of the fruit is X increased by 10\%, i.e, X + \frac{X}{10}.
The increase in price is \frac{X}{10}, and so Chef’s profit will also increase by exactly this amount.
So, the total profit is now
Y + \frac{X}{10}
