Since the painting is hung in center of a rectangular wall ,the distance between them on either side will be the same.so we can divide the length of the painting and wall by 2.we will get 2.4/2=1.2 feet and 20/2=10 feet .10-1.2=8.8 feet gives the distance between the right edge of the painting and right edge of the wall
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.
