Answer 1

present age of A and B :-

5:6

before 5 years their age was:-

4:5

_________________

let their present ages=

5x and 6x

_________________

Solution:-

$\frac{5x-5}{6x-5}=\frac{4}{5}$

Cross multiplication

25x-25=24x-20

25x-24x=(-20)+25

x=5

_______________

their present ages:-

A=5*5=25 years

B=6*5=30 years

Answer 2

Answer:

Step-by-step explanation:

let the ages be 5x and 6x

the ratio of their ages before 5 years is 4:5

(5x -5)/(6x-5) = 4/5

(5x-5)(5) = (6x-5)(4)

25x - 25 = 24x -20

x = 5

their present ages are 25 and 30
