Question

Twice of Chetan's present age is equal to three times of his age four years back. Find his present age.
​

Answer 1

Step-by-step explanation:

Let the present age of chetan be x years.

According to the question,

2x = 3 ( x - 4 )

2x = 3x - 12

3x - 2x = 12

x = 12

Hence,

Present age of chetan = x = 12 years.

Answer 2

Answer:

the present age of Chetan is 12

Step-by-step explanation:

let the age of Chetan is 12 years.

according to the question:

twice of Chetan present age = 3times of his age four years back

Now,

2x=3(x-4)

2x=3x-12( multiple x with 3 and 4 with 3)

3x-2x=12( transfer the variable and constant)

x = 12

Hence, the present age of Chetan is x=12 years.
