Question

x and y are in inverse proportion. If x = 20, then y = 600 . If x = 400, then y = ___​

Answer 1

Answer:

1200

Step-by-step explanation:

As X and Y are inversely proportional

Therefore,

if X = 400 then

value of Y=1200

Answer 2

Answer:

30

Step-by-step explanation:

From this inverse reln, we get

$\frac{x1}{x2} = \frac{y2}{y1}$

$y2 = \frac{x1 \times y1}{x2}$

$y2 = \frac{20 \times 600}{400} = 30$
