The present ages of three persons in proportions 2 : 4 : 6. Eight years ago, the sum of their ages was 36. Find their present ages (in years).	Select
A) 10, 20, 30  B) 16, 28, 36  C) 20, 35, 45  D) 18, 24, 32  E) None of these
Explanation:   Let their present ages be 2x, 4x and 6x years respectively.   Then, (2x - 8) + (4x - 8) + (6x - 8) = 36   12x = 60   x = 5   Their present ages are 2x = 10 years, 4x = 20 years and 6x = 30 years respectively.   10, 20, 30nswer: 10, 20, 30
