78 men can build a 12m long wall in 54 days .How many men will be to build the same wall in 117 days?​

Answer 1

Answer:

36 men

Step-by-step explanation:

78 men took 54 days

Work done in 1 day = 1/54

X men took 117 days

work done in 1 day = 1/117

78/X = 117/54

X = (78x54)/117 = 36 men

Answer 2

Answer:

36 men.

Number of men built 12 m in 54 days: 78

Work done in one day: 1/54

x men took 117 days.

Work done in 1 day:-1/117

78/x=117/54

x=(78×54)/117=36 men's.
