12 workers in 4 hours
1hour is 4/12 = 1/3

15 workers will be 1/3x15= 5 hours.

godofthunder: ha ha it not like that
godofthunder: job done by 1 men = 1/4×12=1/48
godofthunder: we need how much time it takes for 15 so
godofthunder: 48/15= 3 3/15 hours
godofthunder: hope it helps
Navya08: Hahahahha (very )
