PROBLEM:
A sugarcane juicer sells each glass of juice for 50 coins. 20\% of his income is spent on buying sugarcane, 20\% is spent on salt and mint leaves, and a further 30\% is spent on shop rent.
If he sells a total of N glasses of juice, what is his overall profit?
EXPLANATION:
Let’s look at what happens when N = 1. The juicer sells one glass of juice for 50 coins. Then,
- He spends 20\% of 50 on sugarcane, which is 10 coins.
- Another 20\% is spent on salt and mint, which is another 10 coins.
- 30\% is spent on rent, which is 15 coins.
So, his total costs come out to be 10 + 10 + 15 = 35, and hence his profit is 50 - 35 = 15 coins.
Now note that the same calculation applies to every glass sold, so he earns a profit of 15 coins per glass sold. So, his final profit is 15\cdot N coins.

\mathcal{O}(1) per test.
