Suppose father's age = x
Sneh's age is = \(\frac{x}{6}\)
Vimal's age = v
after 10 years Vimal's age = v+10
father's age = x+10
according to question
x+10=2(v+10).................(1)
and v = 8+2 =10
from (1) we get x=30
so, Sneh's age is = \(\frac{x}{6}=\frac{30}{6}=5\)
The correct option is (D): None of these
