7 Years Ago, The Ages (in Years) Of A And B Were In The Ratio 4:5 And 7 Years Hence They Will Be In The Ratio 5:6. The Present Age Of B Is? |
|
Answer» 7 years ago, A's age=4x years and B's age=5xyears so (4x+14)/(5x+l4)=5/6 x = (84 - 70) = 14 B's PRESENT age = 5x + 7 = 5*14 + 7 = 77 years. 7 years ago, A's age=4x years and B's age=5xyears so (4x+14)/(5x+l4)=5/6 => 25x + 70 = 24x + 84 x = (84 - 70) = 14 B's present age = 5x + 7 = 5*14 + 7 = 77 years. |
