Question

present age of mohan and gopal are in ratio 4:5 .eight yearsfrom now the ratio of their ages will be 5:6 . find their present ages.

Answer 1

let the ratio be 4x:5x
eight years from now their ages will be
5x:6x
•let's take the age of mohan to find the value of x
=> 4x+8=5x
=> x= 8

•we can also take the example of gopal's age
=>5x+8=6x
=>x=8

finding present ages
mohan=4×8= 32years
gopal=5×8=40years

Answer 2

Present ages- 4:5

Anil-4x

Rohan-4x

Eight years later- 5:6

Anil- 5x

Rohan- 6x

First let's take Anil.

4x+8 =5x

4x-5x= -8

-x = -8

Therefore, x =8

Rohan

5x+8=6x

5x-6x= -8

-1x= -8

Therefore, x=8

Now, we need to find their present ages.

Anil- 4×8=32 years

Rohan-5×8=40 years

Hope this helps...
