Question

A father's age is thrice the age of his son. After 7 years, the age of the father will be 52 years. What will be the age of his son after 7 years?

Answer 1

lets son age is x
so, 3x + 7=52
=3x=52-7=45
=x=45/3
=x=15
so,15+7=22
therefore,son age after 7 years is 22.

Answer 2

Hey answer is here......☺.......

Let the age of his son be 'x' years.
the age of his father will be 3x
= 3x + 7
The age of the father after 7 years = 52 years.
The age of the son = 3x + 7 = 52
=> 3x = 52 - 7
=> 3x = 45
=> x = 45/3
=> x = 15
so after 7 years the age will be x + 7 = 15 + 7 = 22 years

$so \: the \: age \: of \: the \: son \: is \: 15 \: years \\ after \: 22 \: years \: when \: the \: fathers \\ age \: is \: 52 \: years$
$hope \: helps$
