Question

x and y = complete work in 12 days
x in 30
what is the time taken by y?

Answer 1

Answer:

assume:

work done by X in a day =1/30

work done by Y in a day=1/X

total work together= 1/30+1/X=1/12

to find working days done by Y :

1/X =1/12-1/30

LCM=60

1/X= 5-2/60

1/X= 3/60

1/X= 1/20

working days of Y are 20

Answer 2

Answer:

y=20 hope it is helpful to you
