Q1
C.I = P(1+R⁄4)4t            ------------------(1)
CI – compound interest
P – Principal
R – interest rate
t – time period
a)
From given information, we get
CI = $20000
P = ?
t = 3 years
R = 3.25%
Substituting all the values in (1)
20000 = P(1+0.0325/4)4*4
20000 = P(1+0.0325/4)16
20000 = P(1.008)16
20000 = P(1.008)16
20000 = P(1.13)
P = 20000/1.13
P = 17699.11
Principal is $17699 apx
The amount of Encrypto needed at the beginning of 2022 is $ 17699
b)
From given information, we get
CI = $20000
P = ?
t = 4 years
R = 5%
Substituting all the values in (1)
20000 = P(1+0.05/4)4*4
20000 = P(1+0.0325/4)16
20000 = P(1.013)16
20000 = P(1.013)16
20000 = P(1.23)
P = 20000/1.23
P = 16260.16
Principal is $16260 appx
The amount of Encrypto needed at the beginning of 2022 is $ 16260
