6) Rs. 3000 at 20% interest
7) Rs. 1600 at 40 % interest
8) Rs. 2000 at 60 % interest
9) Rs. 5000 at 6 % interest
10) Rs. 200 at 7 % interest
11) Rs. 500 at 10 % interest
12) Rs. 3600 at 12 % interest
13) Rs. 8400 at 13 % interest
14) Rs. 1200 at 25 % interest
Solution
1) Principal = 500
Rate = 5%
Time = 1 Year
Simple interest = P × R ×T
= 500 × 5/100 × 1
= 225
2) Principal = 1000
Rate = 10%
Simple interest = P × R ×T
= 1000 × 15/100 × 1
= Rs. 100
3) Principal = 1500
Rate = 15%
Simple interest = P × R ×T
= 1500 × 15/100 × 1
= Rs. 225
4) Principal = 600
Rate = 15%
Simple interest = P × R ×T
= 600 × 15/100 × 1
= Rs. 90
5) Principal = 900
Rate = 10%
Simple interest = P × R ×T
= 900 × 10/100 × 1
= Rs. 90
6) Principal = 3000
Rate = 20%
Simple interest = P × R ×T
= 3000 × 20/100 × 1
= Rs. 600
7) Principal = 1600
Rate = 40%
Simple interest = P × R ×T
= 16000 × 40/100 × 1
= Rs. 640
8) Principal = 2000
Rate = 60%
Simple interest = P × R ×T
= 2000 × 60/100 × 1
= Rs. 1200
9) Principal = 5000
Rate = 6%
Simple interest = P × R ×T
= 5000 × 6/100 × 1
= Rs. 300
10) Principal =200
Rate = 7%
Simple interest = P × R ×T
= 200 × 7/100 × 1
= Rs. 14
11) Principal = 500
Rate = 10%
Simple interest = P × R ×T
= 500 × 10/100 × 1
= Rs. 50
12) Principal = 3600
Rate = 12%
Simple interest = P × R ×T
= 3600 × 12/100 × 1
= Rs. 432
13) Principal = 8400
Rate = 13%
Simple interest = P × R ×T
= 8400 × 13/100 × 1
= Rs. 1092
14) Principal = 1200
Rate = 25%
Simple interest = P × R ×T
= 1200 × 25/100 × 1
= Rs. 300
