Answer 1

No introduction is needed. That is the only question you asked.

As for the rest, a simple spread sheet will cover what is going on with the earnings.

Column 1 would be the years [1, 2].
Column 2 would be the month [1, 2, ..., 12, then 1, 2, ... 12 again]

Column 3 would be Ang's salary.
Column 4 would be Bakar's commission.
Column 5 would be Chandran's profit.

I'll leave the math to you.
