Question

After 3 years the age of Ravi will be twice the age of

his son Kunal. If their sum of ages is 60 now, what is the

present age of Kunal?​

Answer 1

Answer:

present age of kunal is 21

Step-by-step explanation:

let age of ravi be x

and age of kunal be y

after 3 yrs,

x+3 = 2y-------1

and x + y =60 so

x=60-y -------2

now substitute x =60-y

so, 60-y+3 =2y

63-y =2y

63=3y

y =21

hope it helps
