| Option | 6 years | correct |
| Option | 7 years | incorrect |
| Option | 8 years | incorrect |
Let 12 years ago age of Badri was X years and age of Budh was 2X.
So, present age of Badri = X + 12
And, present age of Budh = 2X + 12
As per question;
6X + 36 = 4X + 48
2X = 12
X = 6
Present age of Badri = 6 + 12 = 18 years
Present age of Budh = 2*6 +12= 24 years
Required difference between their ages = 24 – 18 = 6 years
