Question

(i) 252 is 35% of a certain number, find the number.
(ii) If 14% of a number is 315; find the number.

Answer 1

(i) Let the number be x
By the given condition,
252 = $\frac{x\times 35}{100}=\frac{x\times 7}{20}$
$\therefore x=\frac{252\times 20}{7}=36\times 20=720$
(ii) Let the number be x
By the given condition,
315 = $\frac{x\times 14}{100}$
$\therefore x=\frac{315\times 100}{14}=\frac{45\times 100}{2}=45\times 50=2250.$ Hence reqd. number = 2250.
