Question

If 8 men can finish a work in 12 days, then find the
number of men required to complete the same work in
5 days?​

Answer 1

In 12 days it takes 8 men to finish the work.So in 1 day, it must take 8*12 = 96 men to finish the work. Obviously to do some work in 1 day you need more manpower.Thus to finish the work in 5 days you would require 96/5 = 19.2 men

Hope it helps

Answer 2

Answer:

Number of men required = 20          

Step-by-step explanation:

Given data

8 men can finish a work in 12 days  

here we need to find how may men required to complete the same work in 5 days  

men          8                   ?                

days         12                 5  

if number of days decreased then number of men will be increased

here number of men is inversely proportional to number of days

          8 × 12 = 5 × ?    

          x =  12 × 8 / 5  =  19 $\frac{1}{5}$  

we can't say 1/5 men

∴ number of men required = 20
