Given:
Rate of interest = 8% compounded continuously.
Amount = 100,000
Time = 25 years
To find:
The principal value.
Solution:
Formula for amount after continuous compound interest:

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting
in the above formula, we get




On further simplification, we get

Therefore, the amount 13533.528 is invested.
Let Universal set U = {1, 2, 3, 4, 5, 6, 7, 8}, A' = {2,5, 6, 7}, A N B = {1,3,4}

Answer:
Hi myself Shrushtee
Step-by-step explanation:
. Please mark me as brainleist
A = 3x
b = 2x+25
180 = a + b
180 = 3x + 2x + 25
180 = 5x + 25
155 = 5x
x = 31
a = 3*31 = 93
b = 2*31 + 25 = 87
