Question

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

Answer 1

Answer:

15.

Step-by-step explanation:

Let the required number of days be x.

More men, Less days (Indirect proportion)

Less hours, More days (Indirect proportion)

Men 36 : 30

:: 16 : x

Hours/ day 8 : 9

Therefore, (36×8×x)=(30×9×16)

Therefore, x = 30×9×1636×8 = 15 days
