P said to q, I am 3/4 times as old as you will be when, i will be 3/2 times as old as you are.what is the ratio of their present ages?

Please give me answer

P : Q
Present : 3/4x : y
Future : 3/2y : x

Difference of ages will constant , present , past , future

3/4x - y = 3/2y - x
3/4x +x = 3/2y + y
7x/4 = 5y/2
Cross multiplication

7x × 2 = 5y × 4
14x = 20y
X/Y = 10/7

Present ages of p : q
3/4×10 : 7
15 : 14 . Answer
