Question

I saw a book marked at ₹ 200 yesterday. I had ₹ 160 with me. What percentage of the existing amount would I require more to purchase that book?

• A. 20%
• B. 15%
• C. 25%
• D. 12%

Answer 1

The correct option is C 25%

The money I have is ₹ 160. The book costs ₹ 200. To match the price of the book, I need ₹ (200 - 160) = ₹ 40.

Now, we need to find what percentage of 160 is 40.
Let that unknown quantity be x.

Now,
$\frac{40}{160}=\frac{x}{100}$

$\Rightarrow x=\frac{40\times 100}{160}=25$

Hence, ₹ 40 is 25% of ₹ 160.
