Question

If 5 men working on a job finish in 32 days find in how many days 8 men will finish the same job in proportion method

Answer 1

OK na its indirect proportion be careful in thinking

Answer 2

Answer:

Number of days = 20

Step-by-step explanation:

Given data

5 men can finish a job in 32 days

here we need to find in how many days 8 men complete the job  

No of men       5                 8

No of days      32               x          [ let x be required days ]  

here job is same but number of men are increased  

therefore, the number days will be decrease

number men is inversely proportional to number of days

            therefore, $\frac{5}{8} = \frac{x}{32}$  

                           32(5) = x (8)

                              x(8) = 32(5)    

                                   x = 4(5) = 20
