the ratio of the ages of 3 people is 4 : 6 : 7 . 8 years ago , the sum of their ages was 44 . find their present ages .
let the present ages be 4 x , 6 x , 7 x . ( 4 x - 8 ) + ( 6 x - 8 ) + ( 7 x - 8 ) = 44 17 x = 68 x = 4 their present ages are 16 , 24 , and 28 . the answer is d .
multiply(6, divide(add(multiply(8, 3), 44), add(add(4, 6), 7)))
