Answer» Answer: 100/11% Step-by-step explanation: For inversely proportional numbers, the PRODUCT of the number must always be constant, if all other conditions are the same. Let x and y be both 10, then xy = Constant => 10x10 = Constant If x increases by 10%, then the new value of x will be 11. And the product of x and y will be 110. But product of x and y should be constant( 100 in this case.) Then y should be decrease to keep the product constant.Now, xy = 100 11y = 100 y = 100/11 And in PERCENTAGE terms [(10 - 100/11)/ 10] x 100 = (10/110) x 100 = 100/11 % |
