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
