Find their age and also find the ratio of their age after 4 years.

Answer 1

let the age of pravin be 3x.

let the age of ritesh be 5x.

3x+5x=48

8x=48

x=48/8

x=6

age of pravin is 3×6=18

age of ritesh is 5×6=30

Answer 2

Step-by-step explanation:

let ratio be x then, 3x ,5x

3x+5x=48

8x = 48

x=6

pravin age =3×6

=18

Ritesh age =5×6

= 30

Age after 4 years

pravin age = 18×4

=72

Ritesh age = 30×4

= 120

ratio = 3:5
