Let
'x' represent the number of shares of stock A
x/2 is the number of shares of stock B
(1/2)(x/2) = x/4 is the number of shares of stock C
5.50x + 5*(x/2) + 10*(x/4) = 420

........
x = 40 shares of stock A
Shanika has 40 shares of stock A, 40/2 = 20 shares of stock B and 40/4 = 10 shares of stock C.
