Explanation / Answer

THE OLD PORTFOLIO HAS BETA OF 1.47

NOW AS ONE MORE ASSET IS ADDED, WE HAVE TO CALCULATE REVISED BETA.

NEW PORTFOLIO BETA = (Weight of existing portfolio x beta of portfolio) + (Weight of newly added stock x beta of stock)

NEW PORTFOLIO BETA = (0.86 X 1.47) + (0.14 X 0.69) = 1.3608 = 1.36

ANSWER : NEW PORTFOLIO BETA = 1.36
