Answer:
Given :
- vimal ia older than aruna by 10 years
- after 7 years it means plus 7 both side
- vimal is twice of aruna's age
answer :
1st
vimal - aruna = 10 [ vimal is big than aruna in age]
vimal = 10+aruna
2nd
vimal +7 = 2( aruna +7 )
10+aruna +7 = 2aruna +14
17 + aruna = 2aruna + 14
2aruna - aruna = 17-14
aruna = 3
vimal = 10 + 3 = 13
right ans = C
