Question

If x and y vary inversly and x =30 , when y = 600 find y and when x =600​

Answer 1

Step-by-step explanation:

If x varies inversely with y

xy=k (constant) ...... (i)

If x=20 and y=600

Xy=20×600=12000

k=12000

When x=400 then from equation (i)

y×400=k

y×400=12000

y=

400

12000

=30
