📊 Work and Time Calculation 📊
A and B’s combined work rate = 1/30 (work done per day)
They worked together for 20 days, so the work done by A and B together is:
20 days × (1/30) = 2/3 of the work
Remaining work = 1 – 2/3 = 1/3 of the work
A finished the remaining work (1/3) in 20 days.
A’s work rate = (1/3) / 20 days
= 1/60 (work done by A per day)
Time taken by A alone to finish the work = 1 / A’s work rate
= 1 / (1/60)
= 60 days
🎉 A alone can finish the work in 60 days. 📊
