If A, B and C have the same amount of land, (B + C) / A = 2
If you meant A, B and C had the same amount of land before A sold his land to B and B to C, the answer is 3
Assume A, B and C each own 12 m2
After selling
A = 9/12
B = 10/12
C = 17/12
This makes (B + C) / A => (10 + 17) / 9 = 3

After even more time, Rohan gained seven pieces, while Pawan gained only four.
