Question

4. If x varies inversely as y and x = 30 when y = 900,

find y when x = 60​

Answer 1

Step-by-step explanation:

Given,

x is proportional to y

i.e xy=k where k is const.

Here

x=30; y=900

therefore 30×900=27000

Now,

x=60

xy =27000

60×y=27000

y=27000/60

y=450

therefore

y=450

Answer 2

Answer:

y = 450............. ..........
