Question

x varies inversely as y, when x = 15 then y = 10, if x = 20 then y = ? ​

Answer 1

Answer:

when x is 15 then y is 10 means the difference is 5 so when x is 20 y is 15

Answer 2

Since x and y vary inversely as each other, therefore the product xy always remains constant.

15*10=20*y

150=20y

y=150/20

y=15/2=7.5
