Calculation:

The average number of bikes sold by P, Q, R and S = {(21 + 19 + 5 + 20)% × 2000} ÷ 4 = 325

So, the average number of bikes sold by T, U, V, and W = (2000 - 1300)/4 = 175

Now, the difference = 325 - 175 = 150

∴ The difference between the average number of bikes sold by P, Q, R and S and the average number of bikes sold by T, U, V and W is 150.
