Option 1 : 82
1) Kartik celebrate his 9th birthday 3 years ago,
Present age of Kartik = 9 + 3 = 12 years
2) After 7 years the Kishan age will be 4 times of Kartik age
7 + Kishan present age = 4 (Kartik present age)
Kishan present age = (4 × 12) - 7
48 - 7 = 41 years.
3) The present age of Ashok is twice the present age of Kishan.
Present age of Ashok = 2 × (Present age of Kishan)
= 2 × 41 = 82 years.
Hence 82 is the correct answer.
