Assume that the price is the same from the beginning of the contract to the expiration of the contract.

1, and the share price is 40+40* 12%*2=49.6 yuan, so the contract price is 49.6 * 100 yuan.

2. The dividend per share is 6*4=24 yuan, and the price per share is 49.6-24=25.6 yuan, so 25.6* 100=2560 yuan.

3.40+40 * per share (12% * 2-4%) = The contract price in 48 yuan is 48 *100 = 4,800 yuan.

4, 59+59* 12%-4*3=54.08 yuan

I think so, too. I don't know if it's right Check the calculation formula yourself.
