Answer 1

☆Your Answer ⛄

→Let the age of Ani and Biju be x and y respectively. Then according to the question-

☞x−y=3...(1)

Dharam is twice the age of Ani

→Hence, age of Dharam =2x

Age of Cathy is half the age of Biju

Then age of Cathy =

$= \frac{y}{2}$

Then according to the question

$2x - \frac{y}{2} = 30$

⇒4x−y=60...(ii)

Subtracting (ii) from (i)⇒x−y−4x+y=3−60⇒−3x=−57

⇒x=

$= \frac{ - 57}{ - 3} \\ = 19$

☞Substitute the vale of x in (i)⇒19−y=3⇒−y=−16

∴ Age of Ani =19 years and age of Biju =16 years.
