x can do one and a half as much of a work which Y can do in one day.Y alone can do a piece of work in 9days .they together can finish that work in.​

Answer 1

Answer:

They both can finish the work in 6 days

Step-by-step explanation:

let the work done by y in one day be 1

thenthe rate of work done by y =work/time

rate=1/1=1

x can do the 1/2 times the work as y in 1 day , so. 1/2*1=1/2

rate of x =1/2/1=1/2

y can do a piece of work in 9 days

so rate =1/9

x can of the half work in 9days

rate = 1/2/9 = 1/18 = 18 days

both can do in

1/18+1/9 days

3/18 = 1/6

1/6 is the rate , so 6 is the number of days
