Answer:
53
Step-by-step explanation:
1) Take the area of the rectangle from origin to Point B. We see that it is 8 * 11 = 88 units of area
2) We subtract all the triangles in the rectangle that are not covered by the shape.
So
- Triangle FAPoint(0,-8) area = 1/2 * 2 * 5 = 5
- Triangle FEPoint(0,-3) area = 1/2 * 3 * 4 = 6
- Rectangle P(0,0) P(0,-3) P(6,-3) P(6,0) area = 6 * 3 = 18
- Triangle DP(6,0)P(11,0) area = 1/2 * 5 * 3 = 7.5
Take the area of the big imaginary rectangle and subtract the area of all the smaller triangles and the smaller rectangle
88 - 5 - 6 - 7.5 - 18 = 51.5
Done!
Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:
Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting 
, we get
Divide both sides by 1.906624.
Therefore, the principal value is about 4563.04.
This only happens when the ordinary ratio is greater than one, the terms of the sequence will get bigger and bigger, and if you add larger numbers you won't get a definitive answer.
