Answer 1

Step-by-step explanation:

x+y=18

y+z=24

z+x =36

2 (x+y+z)=78

x+y+z = 39

x= 39- 24 = 15

y= 18 - 15 = 3

z = 24-3 = 21

Answer 2

Answer:

X's one day's work =121

Let, Y work for x days

∴Y's one day's work =x1

One day work by X and Y together

121+x1=81

x1=81−121=241

∴ x=24 days

∴Y can complete work alone in 24 days.
