Answer 2

Answer:

HOPE IT HELPS

Step-by-step explanation:

Let number of Wells one man can dig in one day be X

12 men can dig 12X Wells in one day and

And (12×14)X Wells in 14 days

This is equal to 5 Wells

i.e, (12×14)X = 5

=> X = 5/168

And 28 men can dig 28X Wells in one day

=> 28 × 5/168

=> 5/6

i.e, 28 men can dig 5/6 Wells in one day

So, they need 10/(5/6) days to dig 10 Wells

=> 12 days

Therefore, 28 men can dig 10 Wells in 12 days.
