The first question: calculate the buying price and selling price of the euro against the pound respectively; Purchase price =1.2111.6349 = 0.7407; Sell =1.2136/1.6331= 0.7431; So EUR/GBP =0.7407/3 1 Question 2: This topic is unit currency: denominated currency, so the purchase price =1.6331* 7.7782 =12.7025; Price =1.6349 * 7.7793 =12.438+083; Therefore, GBP/HKD =12.7025/12.7183 Question 3: Calculate the forward exchange rate for each of the three months separately. The three-month forward exchange rate of USD/JPY is107.50+0.10 =107.60 (buy)107.60+0.28 =107.88 (sell), so USD/JPY. 1.5470-0.0 158= 1.53 12; Therefore, the three-month forward exchange rate between British pound and Japanese yen is1.5299/1.5312; the buying price of Japanese yen =1.5299 *107.60 =164. So the three-month forward exchange rate of British pound and Japanese yen = 1 64.6172/165.1858 Question 4: Similarly,1,the buying price =1.6/kloc-0. Sell =1.6336 *129.39 = 211.37; So pound: yen = 210.8121.372, and the buying price of RMB against yen =129.18/7.2763 =/kloc-0. Selling price =129.39/7.2716 =17.7939; So RMB: JPY = 1 7.7535/17.7939 Question 5: (1) What is the price for banks to buy spot dollars? 1.9335 (2) What is the price for customers to sell 1 month USD? 1.9335-0.0073 =1.9262 (3) What is the price of February dollars sold by banks? 1.9325+0.0132 =1.9457 (4) What is the price of three-month sterling sold by customers? 1 .9325-0.0203 =1.9122 shows that the long-term of this question1is water, not water, but water in February and March respectively. The topic is reversed.
