Answers
Hey Dear,
◆ 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
Thanks dear...
