Given :
Radhika's mother is square the age of Radhika.
5 years hence Mother is 3 times of Radhika.
According to the question :
Let Radhika's age be ' x '
so, Radhika's mother will be ' x^2 '
3 times ( x + 5 years ) = Mother + 5 years
( both will be 5 years older )
Equation :
☞ 3 ( x + 5 ) = x^2 + 5
☞ 3x + 15 = x^2 + 5
☞ x^2 - 3x - ( 5 - 15 )
☞ x^2 - 3x - 10
☞ ( x + 2 ) ( x - 5 )
☞ x = 5
x + 5
☞ 5 + 5
☞ 10.
x^2 + 5
☞ 5^2 + 5
☞ 25 + 5
☞ 30.
Difference = 30 - 10
= 20.
Therefore, In 5 years,the
difference in their age is
20.
