The numbers are less than a third number by 37% and 30%, respectively. By what percentage is the second number more than the first?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 100/9.
Let the third number, c = '100'.
⇒ The first number, a = (100 - 37)% of 100
⇒ a = 63
⇒ The second number, b = (100 - 30)% of 100
⇒ b = 70
% by which b is more than by a is
{(70 - 63)/63} × 100
=7/63 × 100
=100/9
