Question

Aaron alone can finish a piece of work in 12 days and Brandon alone can do it in 15 days ago them worked at it in 15 days if both of them get it together how much time will it take to finish it​

Answer 1

Step-by-step explanation:

aaron=12

brandon=15

LCM, of 15 and 12=60

therfore, aaron per day work = 5 unit per day

brandon = 4 unit per day

they both work for days together thn

per day work = 5+4= 9

so work will complete in 60÷9 6.66 days
