GIVEN: 5 people work eight hours daily and complete a wall in 10 days.
TO FIND: How many days will it take to complete the wall if people work for 4 days?
SOLUTION:
Total work done by the employees when they work for eight hours =
5 × 8 × 10
= 400
Work done in four days = 5 × 8 × 4
= 160
X is the number of days in which the wall can be completed.
Work done by extra people = 10 ×8 × x
Therefore 160 + 80 x = 400
80x = 400 - 160
80 x = 240
x = 3
Wall can be completed in 4 + 3 = 7 days.
These people will complete the wall in 7 days.
