Question

X and Y, working together
, can complete a job in
12 days. X alone can do the job in 18 days. How
much time will Y alone take to complete the job?​

Answer 1

Answer:

Y CAN COMPLETE IN 36 DAYS

Step-by-step explanation:

IF X AND Y BOTH CAN DO IN 12 DAYS

X AND Y CAN DO IN 1 DAY = 1/12

X CAN DO IN 1 DAY = 1/18

TO FIND Y WE NEED TO SUBTRACT X AND Y WORK WITH WORK OF X

THAT WILL BE = 1/12 - 1/18 = 3-2/36

=1/36 ( Y CAN DO IN 1 DAY )

ANS=36 (AFTER RECIPROCAL)

SO, Y CAN DO THIS JOB IN 36 DAYS
