Sneh’s age is $$\frac{1}{6}$$ th of her father’s age. Sneh’s father’s age will be twice of Vimal’s age after 10 years. If Vimal’s 8th birthday was celebrated 2 years ago,then what is Sneh’s present age ?
a) $${\text{6}}\frac{2}{3}{\text{ }}$$ years
b) 10 years
c) 12 years
d) 15 years

Answer: a
Explanation: Vimal’s present age = (8 + 2) years
= 10 years
Sneh’s father’s age = 2(10 + 10) years
= 40 years
Sneh’s age
$$\eqalign{ & {\text{ = }}\left( {\frac{1}{6} \times 40} \right){\text{ years }} \cr & {\text{ = }}\frac{{20}}{3}{\text{years }} \cr & {\text{ = 6}}\frac{2}{3}{\text{years}} \cr} $$
