Question

The road adjacent to badminton court at Central
University, Lucknow, needed repair. So, the university
authorities hired Parikh to do the job. Parikh selected a
certain number of workers and assured the university
that work will be done in 10 days. Unfortunately, 4
workers were absent from the beginning and the task
took 50 days to complete. Can you tell us how many
workers Parikh hired initially.​

Answer 1

Answer: 5

Step-by-step explanation:

Given,

Let x workers complete the work in 10 days.

But, 4 workers were absent from the beginning.

∴ (x - 4) workers completed the work in 50 days.

⇒ x * 10 = (x - 4 )* 50

⇒ x = 5x - 20

⇒ 4x = 20

∴ x = 5

∴ Parikh initially hired 5 workers .
