Question

If 8 men can do a certain job in 12 days, how many men will be required to do the same job in 16 days? what types of proportion​

Answer 1

Answer:

16

Step-by-step explanation:

Time taken by 12 men to construct a wall = 8 days.

Time taken by 1 man to construct a wall = 12×8 days

∴ Time taken by 6 men to construct a wall =

6

12×8

days

=16 days

Answer 2

Answer: 11 men

Step-by-step explanation:

According to the question,

8:12::x:16   (Let the no. of men required in 16 days be x)

Then, Product of means = Product of extremes

So,

 12x = 128

=> x= 10.666667

Therefore, as 10.66667 men are not possible (as human cannot exist in fraction) so the answer will be the nearest round-off which is 11 men... (ans)
