If 8 people complete a work in 5 days, how many days will 10 people take to finish the same work?
A
4
B
5
C
6
D
3
Correct Option:
A
Explanation
Total work = 8 × 5 = 40 person-days. If 10 people work at the same rate, time required is 40÷10=4 days. This is an inverse proportion: more workers, fewer days.
