Question

if 30 men working 9 hours a day , can reap a field in 16 days , in how many days will 36 men reap the field , working 8 hours a day?​

Answer 1

Hi,

15 days

Explanation:

Let's assume F the field

M the number of men

H the time of hours in a work's day

D the number of days worked

k a constant

`F=30*9*16*k\ \Longrightarrow\ k=(F)/(30*9*16) \\\\F=36*8*D*(F)/(30*9*16)\\\\D=(30*9*16)/(36*8) \\\\D=15\ (days)\\`
