Given Data:
- A completes 60% of the work in 45 days
- A and B together finish the remaining 40% of the work in 18 days
Calculations:
Let's first find out how many days A alone would take to complete the whole work:
- A completes 60% of the work in 45 days, so in 1 day A completes 60/45 = 4/3 % of the work
- Therefore, A takes 100 * 3/4 = 75 days to complete the whole work
Now, let's find out how many days B alone would take to complete the whole work:
- A and B together complete 40% of the work in 18 days, so in 1 day they complete 40/18 = 20/9 % of the work
- Since A completes 4/3 % of the work in 1 day, B completes 20/9 - 4/3 = 8/9 % of the work in 1 day
- Therefore, B alone would take 100 * 9/8 = 112.5 days to complete the whole work
Therefore, the correct answer is option D) 112.5 days.
- A completes 60% of the work in 45 days
- A and B together finish the remaining 40% of the work in 18 days

- Therefore, B alone would take 100 * 9/8 = 112.5 days to complete the whole work
Therefore, the correct answer is option D) 112.5 days.
