A’ can do a piece of work in 20 days. ‘B’ can do 80% of the same work ...
Given Information:
- A can do a piece of work in 20 days.
- B can do 80% of the same work in 30 days.
- A and B work together for the entire time.
- They get paid Rs.1610.

Step 1: Calculate the Efficiency of A and B
Efficiency is calculated as the work done per day.

Efficiency of A = 1/20 = 0.05 work/day
Efficiency of B = 0.8 work/30 days = (0.8/30) work/day = 0.02667 work/day

Step 2: Calculate the Total Work
Since A and B work together for the entire time, the total work done is equal to the work done by A in 20 days.

Total Work = Efficiency of A * Number of Days taken by A = 0.05 work/day * 20 days = 1 work

Step 3: Determine the Ratio of Work Done by A and B
Since A and B work together, their work done ratio is equal to their efficiency ratio.

Work done by A : Work done by B = 0.05 : 0.02667 = 1.875 : 1

Step 4: Calculate the Share of A
The share of A can be calculated using the ratio of work done by A to the total work and the total payment received.

Share of A = (Work done by A / Total Work) * Total Payment
= (1.875 / (1.875 + 1)) * Rs.1610
= (1.875 / 2.875) * Rs.1610
= 0.6513 * Rs.1610
≈ Rs.1048.84

Step 5: Final Answer
The share of A in the payment of Rs.1610 is approximately Rs.1048.84.
