Question

10 आदमी एक दीवार को 8 दिन में बना सकते हैं उसी काम को यधे दिन में पूरा करने के लिए कितने आदमियों की आवश्यकता है solve the question

Answer 1

10 people complete it in 8 days.

Then 10×2=20 people complete it in 4 days.

similarly if 20 people are doing the work in 4 days than 40 people will complete the work in 2 days.

in this way it people will complete it in one day and 160 people in 1/2 day.
