1) if $4,500 was invested in a bond fund when the price per share was $9 and $3000 was invested in the fund when the price per share was $10, what was the average (AM) price per share purchased?

1)$9.625
2)$9.50
3)$9.40
4)$9.375---- ans
5)$9.20

$4,500 at 9$/share means you can buy 500 shares. $3000 at 10$/share means you can buy 300 shares. Therefore, average price per share is (4,500 + 3000)/(500 + 300).
=> 7500/800=9.375

No of shares of $9=500
No of shares of $10=300
Average=(500*9+300*10)/800=9.375

These kind of sums which ask for weighted average get repeated very often. I have seen sum of them in PP as well as in this forum. So be clear with the concept guys.
