Question

The ratio between the ages of P and Q is 3:4 respectively. If Q present age is 20 yrs. What will be ratio of ages after 5 years​

Answer 1

Answer:5:4

Step-by-step explanation:

3/4    x/20

3/4 * 20 = x

3/2 * 10 = 4

therefore age of p is 15  

after 5 years

P=20

Q=25

20/25 = 5/4

answer = 5:4

Answer 2

Step-by-step explanation:

Solution :

Let,

• Present age of P = 3x
• Present age of Q = 4x

Q present age is 20 yrs (given)

Age of Q = 4x

4x = 20

x = 20/4

x = 5

• Present age of P = 3x

3 (5)

15

Present age of P = 15 years

After 5 years,

Age of P = 15 years + 5 = 20 years

Age of Q = 20 years + 5 = 25 years

★ Ratio of ages after 5 years =

20/25 = 4/5

4 : 5

Therefore, Ratio of ages after 5 years will be 4 : 5.
