How to solve an inverse proportion
WebIn notation, inverse proportion is written as y ∝ 1 x Example: Suppose that y is inversely proportional to x and that y = 8 when x = 3. Calculate the value of y when x = 10. Solution: Using the fact that the products are constant, we get 3 × 8 = 10y ⇒ y = 24 10 = 2 2 5 Example: It takes 4 men 6 hours to repair a road. WebApr 8, 2024 · When two quantities ‘x’ and ‘y’ are said to be in direct proportion, the relation would be expressed as – k= x/y or, x = ky Example: If Sam gets Rs.2000 for 4 hours of work, how many hours will he have to work to earn Rs.60,000. Sol: k= Number of hours/salary of a worker = 4/2000 = 1/500 By using this relation, x = ky x = 1/500 x 60000 = 12
