Question

Two numbers are less than a third number by $30\%$ and $37\%$ respectively. How much percent is the second number less than the first?

• A. $10\%$
• B. $15\%$
• C. $20\%$
• D. $25\%$

Answer 1

Answer: (A)

$10\%$

Let the $3rd$ number be $100$. Then,

$1st$ number $=70$ and $2nd$ number $=63$

$2nd$ number is less than 1st by $(\frac{7}{70}\times 100)=10\%$
