Question

90 men can complete a work in 24 days
working 8 hours a day. How many men are
required to complete the same work in 18 days working 15/2 hours
​

Answer 1

Answer:

In 24 days, working 8 hours a day, work can be completed by = 90 men

In 1 day, working 8 hours a day, work can be completed by = 90 × 24 men

In 18 days, working 8 hour a day, work can be completed by = (90 × 24)/18 men

‘’ ‘’ “ “ 1 hour “ “ “ “ = (90 × 24)/18 ×( 8 men)

“ “ 7. ½ i.e. 15/2 “ “ = (90 × 24 × 8)/18 × (2/15)

= (90 × 24 × 8 × 2)/18 × 15 = (1 × 24 × 8 × 2)/3 = 128 men
