1.

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

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
