Let X be pair of shoes and Y be pair of boots.   22x+16y = 540 ... eq1   8x +32y = 720....eq 2.   Now multiply eq 1 by 2 and sub eq 2.   44x = 1080   8x = 720.   36x = 360 =&gt; x = 10.   Sub x in eq 2.... we get 80 + 32y = 720... then we get 32y = 640 then y = 20   Differenece between X and Y is 10   Answer : 10
