Question

A and B are working together, they both can do the work in 15 days, if A can do the same work in 24 days, then in how many days will be complete the same work​

Answer 1

Answer:

Step-by-step explanation:

1/15+1/12)x=1

((1*4/15*4)+(1*5/12*5))x=1

(4/60+5/60)x=1

(9/60)x=1

(60/9)(9/60)x=1(60/9)

x=6 2/3 or 6.6666666 days to do the job together

Since we do not take the decimal into consideration , it is 6 days
