If x and y are inversely proportional, find the values of x1, x2, y1 and y2 in the table given below:



















X



8



x1



16



x2



80



Y



y1



4



5



2



y2


8 × y1 = 16 × 5


⇒ y1 = 10


x1 × 4 = 16 × 5


⇒ x1 = 20


x2 × 2 = 16 × 5


⇒ x2 = 40


80 y2 = 16 × 5


⇒ y2 = 1
