Answer 1

Answer:

(a) No of days = 5 days

(b) No of workers = 24 days

● Explanation -

We'll first calculate work hours by 1 person to dig 1 pit.

Work hours = 40 × 10 × 6 / 30

Work hours = 80 hrs

Thus, One person will take 80 hours to dig one pit.

(a) For condition A -

No of days = 80 × 15 / (20 × 12)

No of days = 5 days

(b) For condition B -

No of workers = 80 × 6 / (4 × 5)

No of workers = 24 days

Answer 2

1. Number of days : 5 days

2. Number of workers : 24 workers
