15000 times 1.0 15, and so on = 15225.
5000 divided by 50 times1.01=101.
15225- 10 1= 15 124
Answer B This is a standard algorithm, simple and clear.
also
The price of forward contract 1 month is15000x (1+0.5%) =15075 points.
5000 yuan bonus, a little multiplier 50 yuan, equivalent to 100 points.
Contract price after holding 1 monthly bonus 14975 points.
The price after 14975 for two months is14975x (1+1%) =15124.75 Answer B.
This is a rough algorithm and easy to understand.
There is another algorithm, that is, the bonus of 5,000 yuan after January is equivalent to 100, and the discount of100/.05 is equal to 95.24 points. All the actual Hang Seng points of 65,438+05,000 are only equivalent to 65,438+05.24 = 65,438+0490.
This becomes calculating the price of 14904.76 after three months.
14904.76x (1+6% x0.25) =15128.33 is still extremely close to 15 124.
These two algorithms are used for understanding.
According to general practice, forward contracts are actually calculated by the formula of continuous compound interest.
