Answer:
$3.02 per share
Explanation:
The computation of the earning per share is shown below:
we know that
Earnings per share = (Net income - preferred dividend) ÷  Weighted average outstanding common shares
= ($2,150,000 - $70,000) ÷ 688,000 shares
= $3.02 per share
Date         Particulars      No. of shares
01/01-31/12 610000 ×  12 ÷ 12 (610000 × 1.04)  $634,400
28/02-31/12   63000 × 10 ÷ 12 (52500 × 1.04)  $54,600
01/07-31/12   (2000) ×  6 ÷ 12      -$1,000
Weighted average outstanding common shares 688,000
