A group of workers produces 2,000 lamps per month. Their output was increased by 10% which demanded a production increase of 40 lamps per worker. How many workers are there in the group?

Answer 1

@chasingstars
let x the total no. of workers in a group
2000 lamps is the total no. of lams they can produce before the increase in output
40 lamps is the 10% increase for each worker
2000(10%) = 1/x + 40
