niall ' s income is 60 % less than rex ' s income, and sam ' s income is 25 % less than niall ' s income. if rex gave 60 % of his income to sam and 40 % of his income to niall, niall ' s new income would be what fraction of sam ' s new income?
divide(add(40, 40), add(add(40, 40), const_10))
we can take some easy numbers and make calculations simpler . let r ( rex ' s income ) = 100 q ( niall ' s income ) = 40 % r = 40 s ( sam ' s income ) = 75 % q = ( 3 / 4 ) * 40 = 30 now , if rex gives 40 % to niall - - > q = 40 + 40 = 80 60 % given to sam - - > s = 30 + 60 = 90 the ratio is : q / s = 80 / 90 = 8 / 9 = a
