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

=> 25X + 70 = 24x + 84

x = (84 - 70) = 14

B's PRESENT age = 5x + 7 = 5*14 + 7 = 77 years.

7 years ago, A's age=4x years

B's present age = 5x + 7 = 5*14 + 7 = 77 years.
