Answer:
Interest formula:
SI = P * T * (R / 100)
where,
- P = Principal Amount / Sum
- T = Time period
- R = Rate percent
Solution:
Time period is given as 1 year
Case 1 : Principal = AED 500 & Rate percent = 5%
SI = P * T * R / 100
=> SI = 500 * 1 * (5 / 100)
=> SI = 25
Interest after 1 year = AED 25
Case 2 : Principal = AED 500 & Rate percent = 8%
SI = P * T * R / 100
=> SI = 500 * 1 * (8 / 100)
=> SI = 40
Interest after 1 year = AED 40
Case 3 : Principal = AED 500 & Rate percent = 10%
SI = P * T * R / 100
=> SI = 500 * 1 * (10 / 100)
=> SI = 50
Interest after 1 year = AED 50
Case 4 : Principal = AED 500 & Rate percent = 16%
SI = P * T * R / 100
=> SI = 500 * 1 * (16 / 100)
=> SI = 80
Interest after 1 year = AED 80
Similarly, you can find the interests for other cases.
Case 5 : Principal = AED 1000 & Rate percent = 5%
Interest after 1 year = AED 50
Case 6 : Principal = AED 1000 & Rate percent = 8%
Interest after 1 year = AED 80
Case 7 : Principal = AED 1000 & Rate percent = 10%
Interest after 1 year = AED 100
Case 8 : Principal = AED 1000 & Rate percent = 16%
Interest after 1 year = AED 160
Case 9 : Principal = AED 2500 & Rate percent = 5%
Interest after 1 year = AED 125
Case 10 : Principal = AED 2500 & Rate percent = 8%
Interest after 1 year = AED 200
Case 11 : Principal = AED 2500 & Rate percent = 10%
Interest after 1 year = AED 250
Case 12 : Principal = AED 2500 & Rate percent = 16%
Interest after 1 year = AED 400
OBSERVATIONS:
- As Principal keeps increasing, interest generated increases
- As rate percentage keeps increasing, interest generated increases
Hope this helps!
