Answer #1

Beta of a stock = correlation of stock with market*standard deviation of stock/standard deviation of market

here, correlation of stock A with market = 0.64

standard deviation of stock A = 20%

standard deviation of market = 15%

So, Beta of stock A = 0.64*20/15 = 0.8533

So, beta of stock A is 0.8533
