39. The present value is given by $200000 - 250t$, where $t$ is in days. We are given $t = 200$ days. Substituting this into the equation:<br /><br />Present Value $= 200000 - 250 * 200 = 200000 - 50000 = 150000$ FCFA<br /><br />So the answer is **B. 150000 FCFA**<br /><br />40. Let the first capital be $C_1$ and the second capital be $C_2$. We are given that $C_1 + C_2 = 240000$ and $C_1 = 2C_2$. Substituting the second equation into the first:<br /><br />$2C_2 + C_2 = 240000$<br />$3C_2 = 240000$<br />$C_2 = \frac{240000}{3} = 80000$ FCFA<br /><br />So the answer is **B. 80000 FCFA**<br /><br />41. We are given that 1 Canadian dollar = 375 FCFA. We want to find the value of 5000 Canadian dollars in FCFA.<br /><br />5000 Canadian dollars * 375 FCFA/Canadian dollar = 1875000 FCFA<br /><br />So the answer is **C. 1875000 FCFA**<br /><br />42. We want to find $6\frac{1}{2}\%$ of 100000 FCFA. First, convert the percentage to a decimal:<br /><br />$6\frac{1}{2}\% = 6.5\% = 0.065$<br /><br />Now, multiply this by 100000:<br /><br />$0.065 * 100000 = 6500$ FCFA<br /><br />So the answer is **B. 6500 FCFA**<br /><br />43. The price of the TV set is reduced from 480000 FCFA to 360000 FCFA. The reduction is 480000 - 360000 = 120000 FCFA. The reduction rate is:<br /><br />$\frac{120000}{480000} = \frac{1}{4} = 0.25 = 25\%$<br /><br />Now, we want to apply the same reduction rate to a TV set costing 200000 FCFA. The reduction amount is:<br /><br />$200000 * 0.25 = 50000$ FCFA<br /><br />The new price is:<br /><br />$200000 - 50000 = 150000$ FCFA<br /><br />So the answer is **A. 150000 FCFA**<br />
