Question

Jack's present age
is one fourth of his father's age two years ago.
Jack's father's age will be twice Raman's age after 10 years. If
Raman's 12th birthday was celebrated 2 years ago, then what is Jack's present age?​

Answer 1

Step-by-step explanation:

Let Jack's present Age be J

Jack's father present Age is F

Raman's present age is R

Jack's present age is one fourth of his father's age two years ago. J = (F-2)/4 -----(1)

Jack's father's age will be twice Raman's age after 10 years. F+10 = 2(R+10)

=> (F+10)/2 = R+10

=> F/2 - 5 = R --------(2)

If Raman's 12th birthday was celebrated 2 years ago. R-2 = 12 => R = 14 -------(3)

Putting Value of R in equation 2

F/2 - 5 = 14

F/2 = 19

F = 38 -------(4)

Putting value of F in equation 1

J = (F-2)/4

J = 36/4

J = 9

The present is of Ramen is 14 years.

After 10 year age of Ramen = 10+14=24 years

after 10 years age of father= 2× 24 = 48years

so present age of father= 48-10=38years

so 2 year ago father's age= 38-2=36years.

so present age of Jack = 36/4 =9 years. Answer
