the ratio of ages of rahul and amrita 7 years ago was 17:13 . 4 years hence thier ratio will become. 24:19 . when the ratio of ages of rahul and amrita was 17:13 , the ratio of ages of amit and rahul was 3:5,what is their average age?​

Answer 1

Answer:

Let present Rahul’s age be x and presemt Rohit’s age be y

x/y=3/7

i.e. 7x=3y—————————————1

After 5 years…

Rahul’s age — x+5

Rohit’s age— y+5

Now (x+5)/(y+5)=1/2

2x+10=y+5

2x-y+5=0 —————————————-2

Now on solving 1 and 2 we get

x=15 and y=35

Difference in their ages 35-15=20
