PLEASE ANSWER THE QUESTION WITH SOLUTION ​

Answer 1

Answer:

27

Step-by-step explanation:

if the ratio of their ages is 2:3

Let their ages be 2x and 3x

p = 2x

Q = 3x

after 18 years their ages would be

P = 2x + 18

Q = 3x + 18

it is given that the ratio of their ages after 18 years is 4:5

Hence

2x + 18/ 3x + 18 = 4/5

5(2x + 18) = 4(3x + 18)

10x + 90 = 12x + 72

2x = 18

x = 9

Present age of Q is

3x = 3(9) = 27
