Answer 2

Answer:

After 5 years ages ratio of p and q = 4:5

Step-by-step explanation:

At present:

Ratio between ages of p and q is 3:4 (given)

Let age of p = 3x,

age of q = 4x

=> 20 = 4x

/* q's present age = 20 */

=> 20/4 = x

=> 5 = x ---(1)

Now ,

p's age = 3x = 3×5 = 15

q's age = 20

After 5 years :

p's age = 15+5 = 20

q's age = 20+5 = 25

Ratio of their ages = 20:25

= 4:5

Therefore,

After 5 years ages ratio of p and q = 4:5
