Question

If x varies inversely as y and y=60 when x=1.5. Find x when y=4.5.​

Answer 1

∴ xy = k (constant) If x = 1.5 and y = 60 ∴ xy = 1.5 x 60 = 90 ⇒ k = 90 When y = 4.5, then from Eq.(i), 45 × y = k ⇒ 45 × y = 90 ⇒ y = 90/4.5 = 20Read more on Sarthaks.com - https://www.sarthaks.com/860074/if-x-varies-inversely-as-y-and-y-60-when-x-1-5-find-x-when-y-4-5
