In second case orange left with fruit seller  = M = [((100 - 20)% of N) – 2]
Finally orange left with fruit seller, 5 = (100 - 90)% of M
So combining all three conditions =

Short trick :
Start from Third customer →
After selling oranges to third customer,
he left with 10% = 5 oranges.
100% = 50 oranges
Now,
Before selling oranges to 2nd customer he has oranges,
80% → 50 + 2 free oranges
100% → 65 oranges.
Now,
Before selling oranges to 1st customer he has oranges,
