Question

Two years ago amar was five times as old as karan afrer one year from now dheeraj will ne thrice as old as karan . If after 3 years karan becomes 10 years old what is difference between the present age

Answer 1

Let present age of Amar be x

Let present age of Karan be y

Two years ago their age were,

(x-2)=5(y-2).....{1}

Let present age of Dheeraj be z

After a year the ages will be,

(z+1)= 3(y+1)......{2}

After three years Karan will be 10 years old.

Therefore, y+3=10

y=7......{3}

From {1} &{2} we get,

(x-2)=5(y-2)

x-2=25

x=27

From {2} & {3} we get,

(z+1)=3(y+1)

(z+1)=24

Z=23

Amar is 20 years old than Karan.

Dheeraj is 16 years old than Karan.
