Let joyal's present age be x
Then, mother's presnt age is 3x
Age of joyal after 5 years = x + 5
Mother's age after 5 years = 3x + 5
Sum of their age after 5 years = 66
x + 5 + 3x + 5 = 66
4x + 10 = 66
4x = 66 - 10
4x = 56
x = 56/4
x = 14
So, joyal's present age = 14 years
And, mother's present age = 3 × 14
= 42 years
