If x and y are inversely proportional then: *
WebIf two quantities x and y vary directly with each other, then (a) x/y remains constant. (b) x – y remains constant. (c) x + y remains constant. (d) x × y remains constant. Answer: When two quantities x and y change in direct proportion to one another, their corresponding values stay constant. (a) x/y remains constant. WebCalculation: Given that x and y are inversely proportional. ⇒ x α 1/y ⇒ x = k/y where k is constant ⇒ xy = k ∴ Product of x and y is constant Download Solution PDF Latest CTET Updates Last updated on Apr 1, 2024 CTET Notification 2024 Is To Be Out Soon!

Since y = 2 when x = 8, 2 = k 8 ⇒ k = 16 Now, we know the complete formula y = 16 x. If x = 12, then y = 16 12 = 4 3. I hope that this was helpful. Answer link
WebWith direct proportionality we have c = x / y which we can also express that as c / 1 = x / y and solve for c using the calculator above. If y = 5 for x = 20, then we have c / 1 = 20 / 5 hence c = 4. With inverse proportionality c = x · y which we can also express that as c / x = y / 1 and again solve for c.
