Ramu is now half old as as his father . twenty years ago Ramu's father was six times ramu's age. what are their ages

Answer 1

So the father is now twice as old as his son

son's age ---- x
father's age ---- 2x

Twenty years ago :
son's age = x-20
father's age = 2x-20

2x-20 = 6(x-20)

solve for x, etc

Answer 2

but its given six times . explain me more better

Answer 3

but its given half of ramu . explain me more better

Answer 4

Ummmhh,
if you are half as old as your sister, wouldn't your sister be twice as old?? . I defined it the way I did to avoid fractions.

What does 6(x-20) mean?
Does it not say 6 times (the son's age) ??

2x-20 = 6(x-20)
2x-20 = 6x - 120
-4x = -100
x = 25

So the son is now 25 and the father is 2x or 2(25) or 50

check:
how old was the son 20 years ago? He was 5
how old was the father 20 years ago? He was 30
Was he not 6 times as old as his son ????
6 times 5 = 30
