Answer 1

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!
