The ratio between the present ages of P and Q is 4 : 5 respectively. Four years hence Q will be five years older than P. What is P’s present age?1). 15 years2). 20 years3). 25 years4). Cannot be determined

Answer»

<P>The ratio of their ages is 4:5 so let their respective ages be p and Q so we have,

p/q = 4/5

⇒ 5p = 4q

⇒ 5p/4 = q

Four years LATER

(p + 4) + 5 = q + 4

⇒ p + 5 = 5p/4

⇒ p/4 = 5

⇒ p = 20
