Question

x varies inversely as Y, when x=25 then y=10, if x=20 then Y=?plz fast solve this question I mark u brainlist. plz easy method se karna

Answer 1

Given that x varies inversely as y.

⇒ x = k/y

⇒ 25 = k/10

⇒ k = 250.

So, the equation becomes x = 250/y.

When x = 20.

⇒ 20 = 250/y

⇒ y = 12.5.

Therefore, the value of  y = 12.5.

Hope this helps!
