Question

present age of chintu mother is four times chintu age.five year hence her age will be 21 more than chintu age.find their present age

Answer 1

Let present age of Chintu be x
Age of his mother = 4x
After 5 years, age of chintu = x+5
age of his mother = 4x+5
But according to question,
Age of his mother = x+5+21 = x+26
Accordingly,
x+26 = 4x+5
x = 7
Age of chintu = 7yrs
Age of chintu's mother = 4*7 = 28yrs

Answer 2

Let chintu age be x years
then
Chintu's mother age =4x years
Now,21
5 year hence
(4x+5) - (x +5) = 21
3x = 21
x = 7
Hence present age of chintu = x years= 7 years
And her mother age= 4x =4(7) = 28 years
