Question

Mark (✓) against the correct answer
5% of a number is 9. The number is

(a) 120
(b) 140
(c) 160
(d) 180

Answer 1

(d) 180

Let the required number be x. Then, we have:
5% of x = 9
⇒ $\left(\frac{5}{100}\times x\right)=9$
⇒ x = $\left(9\times \frac{100}{5}\right)=\left(9\times 20\right)=180$
