Ans is 5.

1st Round:
Ranjeet: 45,
Abu:55 (15 marks higher than Ah long),
Ah Long:36 (20% lower than Ranjeet, 20% of 45=9,45-9=36)

2nd Round:
Ranjeet: 76,
Abu: 95,
Ah long: 76 (For second round, Abu scores higher than others, while Ah Long and Ranjit shares the same marks with 95 and 76 marks respectively)

Last Round:
Ranjeet: 40 (40% of total marks 100=40)
Abu: 0 (Abu didn't get any mark)
Ah long: 44 (10% of 40=4, so 40+4=44)

Now total marks by Ranjeet=45+76+40=161
total marks by Ahlong=36+76+44=156

Difference=5.
