Dida is now three times as old as his brother and four times as old as his son. Eight years from now, Dida’s age will be twelve years more than the sum of the ages of his brother and his son. Find Dida’s present age.

Answers

Chrispoh
Let Dida's age be y.
His brother's age will be 1/3 y
and dida's son's age will be 1/4 y

In twelve years time,
Dida's age will be (y+8) years.
His brother's age will be (1/3 y +8)
and dida's son's age will be (1/4 y +8)

(y+8) - 12 = [(1/3y +8) + (1/4 y +8)]

y - 4 = (7/12 y +16)

y - 7/12 y = 16+4

5/12 y = 20

y= 20 x 12/5
= 48.
Dida is 48 years now.
