Question

5 men working 8 hours a day can completely build a wall of length 20 meters, breadth ¼ meter and height 6 meters in 3 days. How many days will 8 men working 6 hours a day require to build a wall of length 120 meters, breadth ½ meter, and height 4 meters? (1 Point)

Answer 1

Step-by-step explanation:

Given 5 men working 8 hours a day can completely build a wall of length 20 meters, breadth ¼ meter and height 6 meters in 3 days.

• Given  
• 5 men ----------8 hrs------3 days will build a wall of length = 20 m, breadth = ¼ m, height = 6 m
• 8 men ----------6 hrs------? Days to build a wall of length = 120 m, breadth = ½ m, height = 4 m
• Now we need to find the number of days to build
• Let the number of days be D
• So length, breadth and height = Men and time
• We can put the equation as  
• 20 x ¼ x 6 / 120 x ½ x 4 = 5 x 8 x 3 / 8 x 6 x D
• 30 / 240 = 5 / 2D
• 60 D = 5 x 240
• Or D = 5 x 240 / 60
• Or D = 20 days.

Therefore 20 days is required to construct the wall
