Question

the age of Sohanlal is 4 time of his son Amit if the difference of their age is 27 find the age of Amit

Answer 1

(P.S. Don't get confused: "X" means multiplication and "x" is the variable)
Let the age of Amit be x
Then the age of Sohanlal is 4x
ATQ,
x-4x=27
=>-3x=27
=>x=27/-3
=>x=9
Therefore,the age of Amit is 9
And the age of Sohanlal is 9X4=36
