- Krish can complete the entire work in 4 days. Hence, his work rate is 1/4 of the work per day.

- Rishi can complete the entire work in 6 days. So, his work rate is 1/6 of the work per day.

- Working together, their combined work rate is 1/4 + 1/6.

- Simplifying: (3/12) + (2/12) = 5/12 of the work per day is completed together.

- Rishi's share of the work is (1/6) / (5/12) = 2/5.

- Rishi's share of the total payment is (2/5) * Rs1,600 = Rs640.

- Option 1: Rs640 is the correct answer.
