Question

The ratio between the present age of p and q is 3:4 respectively. If q s present age is 20 years what will be the ratio of the age after 5years

Answer 1

Lets take their present ages as 3x and 4x. q's present age is 20. So, 4x= 20. x=5. So, now p's present age is 3x that is 3×5=15. So, their ages after 5yrs are p= 15+5=20 and q=20+5=25. So, the ratio of their ages after 5yrs is 20:25, that is 4:5.

Answer 2

Answer:

The ratio of the age after 5 years is 4:5

Step-by-step explanation:

The ratio between the present age of p and q is 3:4 respectively.

Let the ratio be x

So, p's present age = 3x

q's present age = 4x

We are given that q's present age is 20 years

So, $4x=20$

$x=5$

So, p's present age = 3x=3(5)=15

Ages after 5 years

p's age = 15+5=20

q's age = 20+5=25

The ratio of the age after 5 years = 20:25 = 4:5

Hence the ratio of the age after 5 years is 4:5
