Question #316364

1. If the discounted amount is ₱8500 while the discount rate is 22% then what is the future amount of the money?




2. Compute the annuity of the money which has future worth of ₱50 000 in 5 years if it compounded monthly at the rate of 11%?






3. What is the equivalent effective rate of interest compounded quarterly if the nominal rate is 14.5%?

  1. discounted amount = 8500

discount rate = 22%

future value = 100%

10022=78100-22=78

78% = 8500

100% = x

7878% * x= x=8500100*x= 8500*100

78x=85000078x=850000


78x78=85000078​ \frac{78x}{78} = ​ \frac{850000}{78}


x=10897.4359x=10897.4359

The future value is approximately P10897.


2.Future value (FV) = 50000

time n= 512=605*12=60

interest rate = 11%

monthly interest rate = 11/100÷1211/100÷12== 0.009166

present value (PV)

PV=FV[1(1+r)nPV = FV[\frac{1}{(1+r)^n} ]

(1+r)n=(1+0.009166)(1+r)^n= (1+0.009166) 60 =1.728916


PV=50000[11.728916]PV= 50000[\frac{1}{1.728916}]


= 28919.8595

The present value is approximately 28919.86


3.

Nominal rate (r)= 14.5%

Compounding (m)= 4/yr

effective rate interest (i)

i=(1+rmi= (1+\frac{r}{m} ) m -1


i=(1+0.1454i=(1+\frac{0.145}{4})4 -1


i=0.15307664i=0.15307664

I= i100i*100

I=0.15307664100= 0.15307664*100

= 15.307664

The effective interest rate is approximately 15.3077%
