vishwa23: 4x+5/5x+5=5/6
vishwa23: cross multiplication
vishwa23: 6(4x+5)=5(5x+5)
vishwa23: 24x+30=25x+25
vishwa23: 24x-25x=25-30
vishwa23: -x= -5
vishwa23: - x = -5 so, both the side so, cut them
vishwa23: the value of x is 5
vishwa23: so, now the present age of A is 4(5)=20 yrs

Let the common ratio be x.

Let the present ages of A and B are 4x and 5x.

Given that After 5 years, they will be in the ratio of 5:6.

 \frac{4x+5}{5x+5} = \frac{5}{6}

On cross-multiplication, we get

6(4x+5) = 5(5x+5)

24x + 30 = 25x + 25

24x = 25x - 5

24x - 25x = -5

-x=-5

x = 5.


Therefore the present age of A = 4(5)

                                              = 20 years.


Hope this helps!
