anyone pls tell me fast​

Answer 1

Step-by-step explanation:

Given :

Deepak present age one - third

Mother age five time his age 6 year

Find :

Present Age

Solution :

Let present age be X year

Deepak age = X / 3 year

6 year ago = X / 3 - 6 year

Mother age = ( X - 6 ) years

Deepak age = ( X / 3 - 6 ) years

5 ( X / 3 - 6 ) = ( X - 6 )

5 ( X - 18 ) / 3 = ( X - 6 )

5 X - 90 = 3 ( X - 6 )

5 X - 90 = 3 X - 18

5 X - 3 X = 90 - 18 ( Variable and Digit each other side )

2 X = 72

X = 72/2

X = 36

Therefore Mother age X = 36 year

Deepak age = X / 3 = 3

Putting Value X in Equation

36/3 ( cancel 3 by 36 )

12 years

The Present age 12 years

Answer 2

Answer:

Given :

Deepak present age one - third

Mother age five time his age 6 year

Find :

Present Age

Solution :

Let present age be X year

Deepak age = X / 3 year

6 year ago = X / 3 - 6 year

Mother age = ( X - 6 ) years

Deepak age = ( X / 3 - 6 ) years

5 ( X / 3 - 6 ) = ( X - 6 )

5 ( X - 18 ) / 3 = ( X - 6 )

5 X - 90 = 3 ( X - 6 )

5 X - 90 = 3 X - 18

5 X - 3 X = 90 - 18 ( Variable and Digit each other side )

2 X = 72

X = 72/2

X = 36

Therefore Mother age X = 36 year

Deepak age = X / 3 = 3

Putting Value X in Equation

36/3 ( cancel 3 by 36 )

12 years

The Present age 12 years
