Peter : 4u
Ravi : 5u

Peter's 1u = Ravi's 1u + $106
Peter's 4u = Ravi's 4u + $106 x 4
= Ravi's 4u + $424

Total = Ravi's 5u + Ravi's 4u + $424
= $424 + 9u
= $1000

Ravi's 9u = $1000 - $424
= $576

Ravi 1u = $576 ÷ 9 = $64


Difference between Ravi's and Peter's money = 4u + $424 - 5u
= $424 - 1u
= $424 - $64
= $360
