Missing information in question:
Otis Thorpe Corporation has 10,000 shares of $100 par value, 8% preferred stock and 50,000 shares of $10 par value common stock outstanding at December 31, 2014.
The journal entry is as follows:
8% Preferred Stock A/c Dr. $400,000
To Common Stock A/c $280,000
To Paid in Capital in excess of par value $120,000
(Being 4,000 shares of Preferred stock has been converted in to Common Stock)
Workings:
Preferred Stock = 4,000 shares × $100
= $400,000
Common stock = 4,000 × 7 shares × $10
= $280,000
