Question

30. The age of Mr Vinod is four times that of his son Rohit. If the difference of their ages is 27
years, find the age of Rohit.​

Answer 1

Answer:

9 years

Step-by-step explanation:

Let the age of rohit be x yrs

A/q

Mr vinod age = 4x yrs

now,

(x-4x) = 27

3x = 27

x = 9

hence, age of rohit is 9 yrs

Answer 2

Answer:

Let the age of Mr.Vinod be x years and his son Rohit' s age be y years

According to the first condition

x = 4y.....(1)

According to the second condition

x- y = 27....(2)

By substituting the value of x in (2)....(from 1)

4y - y = 27

= 3y = 27

Hence y= 9

Hence the age of Rohit = y years = 9years.
