 a bond of a pharmaceutical company for 5000.

The bond yield 4% per year
Dividend  = 200

. The stock sells at $20 per share
 and earn a dividend of 0,50 per share per year.

Let x be the number of shares he has to buy

The value of shares to be purchased = 20x

20x +5000 should fetch him 3 % or more

Interest to be earned 3%(20x+5000)

2.5% 20x +4% 5000 = 3%(20x+5000)

2.5*20x +20000= 60x +15000

10x =5000
x=500
More than 500 shares

Investment in shares =500*20 10000
Dividend on shares = 2.5% = 250
Interest on bonds = 200

Total income = 450 on investment of 15000 =3 %
