183,450 shares
Solution:
The following is the approximation of the weighted average share number:
January 1 to April = 138,000 shares for 4 months = 46,000 shares
May to June = 72,000 shares + 138,000 shares
= 210,000 shares for 2 months = 35,000 shares
July to September = 210,000 shares - 10,200 shares
= 199,800 shares for 3 months = 49,950 shares
October to December = 199,800 + 10,200 shares
= 210,000 for 3 months = 52,500 shares
Now weights average number of shares is 183,450 shares
