Question

if 27 men can finish a part of work in 64 days,then how many more men are needed to finish the same part of work in 36 days

Answer 1

Answer:

21 men

Step-by-step explanation:

* As it is clearly a case of inverse variation thus we wrote 27 X 26 = x X 36

* 1 = 27

* 2 = x = 48

* 48-27 to find the number of extra men required to finish the part of work in 36 days

Answer 2

Answer:

21 days

Step-by-step explanation:

64 days = 27 men

36 days = x men

so in this case its inverse variation

64×27 = 36×x

64×27/36 = 48

so 48 men are required

so more men = 48-27=21
