Question

The following question is based on the following information about the stocks of KT Corporation, International Flavors & Fragrances, and Quality Systems.

You invested a total of $11,600 in shares of the three stocks at the given prices, and expected to earn $272 in annual dividends. If you purchased a total of 200 shares, how many shares of each stock did you purchase?

Price Dividend Yield KT (KT Corporation) $16 7% IFF (International
Flavors & Fragrances) $56 2% QSII (Quality Systems) $80 2%

Explanation / Answer

Let x shares of KT , y nos. of shares of IFF and z shares of QSII

x +y + z = 200 ------(1)

KT @ $ 16 : 16x

IFF @ $ 56 : 56y

QSII @ $ 80 : 80z

16x +56y + 80z = 11600 -----(2)

Dividend : 16*0.07x + 56*0.02y + 80*0.02z = 272

1.12x + 1.12y + 1.6z ----(3)

We have 3 unknown and 3 equations :

x = 50 ; y = 50 ; z = 100

KT = 50 shares ; IFF = 50 shares ; QSII = 100 shares
