As you see, q is not a function of p. In addition to p, you need to know X / Y.

We known p, how to determined q (in function of p)? Peter sal. X John sal. Y X+pX=Y-qY ... ? qY= Y- X- pX q= (Y- X- pX)/Y gives q as a function of p, for fixed X and Y
Since the increase and decrease are in percentage thus we should have X + p%X = Y - q%Y That gives X + pX/ 100 = Y - qY/100 qY/100 = Y - X - pX/ 100 Now proceed further
