D) Vivek is 30 years younger than his father. After 10 years their ages will be in the ratio 1:2. Find their present ages.

I think Vivek is 20 and his father is 50

Because 30 + 30 equals 60 as he has to be half his age he'll be 30 but that's in 10 years time. you just subtract 30 and 60 by 10 and you'll get 20 and 50

Vivek:20 years

Father:50 years

Step-by-step explanation:

Since it is a age question, their difference do not change, so

2-1=1 (difference in ratio)

1u=30

Vivek now:30-10=20 years

Father: 30x2=60

60-10=50 years

Hope this helps! Thanks.
