🕒 Work and Time Calculation 🕒

A’s work rate = 1/23 (work done per day)

Since A is 30% more efficient than B, B’s work rate is:

B’s work rate = A’s work rate / 1.3

= (1/23) / 1.3

= 1/29.9 (work done per day)

Combined work rate of A and B = A’s work rate + B’s work rate

= 1/23 + 1/29.9

= (29.9 + 23) / (23 × 29.9)

= 52.9 / 687.7

= 1/13 (work done per day)

Time taken by A and B to complete the work = 1 / Combined work rate

= 1 / (1/13)

= 13 days

🎉 A and B, working together, will take 13 days to complete the job. 🕒
