Question

A father is 3 times as old as his son.In 12 years time, he will be twice asold as his son. Find the present ages of father and son

Answer 1

Answer:

★ Let the Present Age of Son be n years.

⇴ Father = 3 times of Son

⇴ Father = 3 × n

⇴ Father = 3n

__________________

☯ AFTER 12 YEARS :

↠ Father = Twice of Son

↠ (3n + 12) = 2 × (n + 12)

↠ 3n + 12 = 2n + 24

↠ 3n – 2n = 24 – 12

↠ n = 12

━━━━━━━━━━━━━━━━━━━━━━━━

◉ PRESENT AGES :

◗ Son = n = 12 years

◗ Father = 3n = 3(12) = 36 years

∴ Present age of Dad & Son is 36 & 12 yrs.

Answer 2

Then,His Father present Age is 3 Time = 3x

$\rule{100}{5}$

$\large{\underline{\red{After\:12\:year}}}$

A.T.Q

• 3x + 12=2( x + 12)
• 3x + 12=2x + 24
• 3x - 2x=24 - 12
• x=12
