H = V/B

The base of the prism is given by the expression 2X^2+8x-9
then c)5x+3
Given:
Principal = Rs. 2000
Rate of interest = 20% p.a. compounded quarterly.
Time = 1 year
To find:
The compound interest.
Solution:
Formula for amount:

where,
P = Principal
r = Rate of interest
t= Time
n = number of times interest compounded in an year.
Putting P=2000, r=0.2, n=4 and t=1, we get




Now, the compound interest is



Therefore, the compound interest is Rs 431.0125.
100 is 105 rounded to the nearest hundred hope it helped
