Answer:
$3,500,000
Explanation:
the total number of shares
= 200000 + 100000 + 400000
= 700000 shares
value of 400000 shares = 2 million dollars
such that 1 share = 2 million/400000
= 5
total value of the shares = 5 * 700000
= $3,500,000
therefore we conclude that the post money valuation of this company is $3,500,000
