-3. On what sum will the difference between the simple and compound interest for 3
years at 10% p.a. is Rs 232.50?
Answers
simple interest :
years percentage. Amount
(3 years). (10%). 232.50
1 st year. 10%. (232.50)*(10%)= 23.25
2 nd year. 10%. (232.50)*(10%)=23.25
3 rd year. 10%. (232.50)*(10%)=23.25
Simple Interest= 23.25+23.25+23.25
Simple interest = Rs 69.75
compound interest :
years percentage. Amount
(3 years). (10%). 232.50
1 st year. 10%. (232.50)*(10%)= 23.25
2 nd year. 10%. (232.50+23.25)*(10%)=25.575
3 rd year. 10%. (255.75+25.575)*(10%)=28.1325
Compound Interest= 23.25+25.575+28.1325
Compound interest = Rs 76.9575
Difference =SI(Simple Interest)-CI (compound interest)
= 69.75 - 76.9575
= -7.2075
