Answer 1

$\large\bf\underline{Given:-}$

• Age of farther is 3 times as old as his son.

• After 12 year's father will be twice as old as his son.

$\large\bf\underline {To \: find:-}$

• Present age of son.

$\huge\bf\underline{Solution:-}$

• Let the present Age of son be x years
• So his Father's present age is 3x

According to question:-

After 12 years age of father will be twice as old as his son.

• Age of son = x + 12
• Age of father = 2(x + 12)

we know that present age of father is 3 times his son's age = 3x after 12 years father's age will be 3x + 12.

»» 3x + 12 = 2(x+12)

»» 3x + 12 = 2x + 24

»» 3x - 2x = 24 - 12

• »» x = 12

Hence,

present age of father:-

• 3x = 3 × 12 = 36years.

✝️ Present age of son (x) = 12 years.
