Q1. ANSWER
Let Ramu’s age be ‘x’, then his fathers’ age be 6x and let his mother’s age be y.
According to the given condition;
Sum of their present ages = 70
ie, x + 6x + y = 70
Let after ‘k’ years father’s age is twice of his son’s age.
So, after k years,
Father’s age = 6x + k = 6x + 4x = 10x
Son’s age = x + k = x + 4x = 5x
And mother’s age = y + 4x
According to the given condition;
after k years, sum of their ages = 142
ie, 10x + 5x + y + 4x = 142
Now, 2 – 1=12 x = 72
Hence son’s present age is 6 years,
then father’s present age is 6x = 6 x 6 =36 years.
