Answer 2

Given info : 500 workers complete a job in 46 days.

To find : How many more workers will be required to complete the same job in 19 days.

solution : let x workers complete the same job in 19 days.

∵ 500 workers complete a job in 46 days

∴ 1 workers complete the job in 46 × 500 days

∴ x workers complete the job in 46 × 500/x days

but x workers complete job in 19 days

so, 46 × 500/x = 19

⇒x = 46 × 500/19 = 1210.52

so workers should be 1211 [ workers can't be fraction, as you know ]

Therefore 711 more workers will be required to complete the same job in 19 days.
