Calculate a price-weighted index of the three stocks based on the information provided.

Stock	P(0)	Q(0)	P(1)	Q(1)	P(2)	Q(2)
A	70	200	72	200	72	100
B	85	500	81	500	81	500
C	105	300	98	300	98	300

A. the rate of return for the first period (t = 0 to t= 1).

B. the value of the divisor in the second period (t = 2). Assume that Stock A had a 1-2 reverse-split during this period.

C. the rate of return for the second period.
