Question

Sushil is now 4 times old as Sunil. 5 years ago was 7 times as old as Sunil was then what is the present age of Sunil

Answer 1

let Sunil's age be x.

then,. Sushil's age = 4x

5yrs ago,

Sunil's age = x -5

sushil's age = 4x -5

A/q

4x -5 = 7(x -5)

4x -5 = 7x -35

7x-4x = 35-5

3x = 30

x = 10

Sunil's present age = 10 yrs

Sushil's present age= 4×10 = 40yrs

Answer 2

Answer:

let sunil's age be x

then sushil's age will be 4x

Five yrs ago,

sunils age=x-5

sushils age=4x-5

now,

according to the question

4x-5=7(x-5)

4x-5=7x-35

35-5=7x-4x

30=3x

x=10

therefore sunil's age is 10 years
