2. Consider the three stocks in the following table. (show calculations)

Stock	Shares Outstanding (in million shares)	Price ($)
		t=0	t=1
K	90	32	40
M	30	90	85
R	55	41	47

(a)Calculate the rate of return on a price-weighted index of these three stocks from t=0 to t=1. (Assume a divisor of 3)

(b)Calculate the rate of return on a value-weighted index of these three stocks from t=0 to t=1. (I think the answer is 16.5 but not sure)

(c) Calculate the rate of return on an equally-weighted index of these three stocks from t=0 to t=1. Show calculations using both arithmetic average and geometric average.
