First of all, let me clarify your question: You bought 20,000 shares of Dongfang Electronics at the price of 6.3 yuan, and now the share price has risen to 7.35 yuan. You need to calculate how much money you made in this investment.

We can use the following formula to calculate:

Earnings = (selling price-buying price) * number of shares

Substitute your question into this formula:

Income =(7.35-6.3)*20000

Next, we calculate the result:

Income =1.05 * 20000 = 21000 yuan.

So, you earned 2 1000 yuan from this investment.
