Question

In a certain factory there are 96 workers. The ratio of blue-eyed to brown-eyed workers is 3:5. If all the workers have either blue or brown eyes, how many have brown eyes?​

Answer 1

3k+5k=8k
96/8=12
k=12
as we know blue-eyed are 3k and brown-eyed 5k so we need to put 12 instead of k
5x12=60
