Question

if x varies inversely as y when x =40, and y=600,then find y ,when x=400 . with explanation ​

Answer 1

Answer:

60

Step-by-step explanation:

Two equations are said to be in inverse proportion if xy=k, where k is a constant value.

When x=40, y=600

Therefore, when x=400, y =

40×600=400×y

⇒24000=400y

⇒y=24000/400

⇒y=60

Answer 2

Answer:

So here's the answer

Step-by-step explanation:

As it's a case of inverse variation..

40*600=400*y

24000/400=y

60=y
