Question

If $11\%$ of a number exceeds $7\%$ of the number by $18$, the number is

• A. $72$
• B. $360$
• C. $450$
• D. $720$

Answer 1

The correct option is C $450$

Let the number = x

11 % of number $=11x/100$

7 % of number $=7x/100$

According to the problem 11 % of number exceeds 7 % is 18.

$\frac{11x}{100}-\frac{7x}{100}=18$

$11x-7x=1800$

$4x=1800$

$x=450$

$\therefore$ Required number is $450$
