1. Rs. 8
2. Rs. 6
3. Rs. 4
4. Rs. 9
Answer & Explanation Explanation :- Answer:- 2 P = 500 R = 6% Total Days = 28+30+15 = 73 T=73/365 2. Find the Simple Interest on Rs. 7500 at 11% for 2 Years and 5 months. Answer & Explanation Answer:- 4 Explanation :- P = 7500, R = 11 , T = 2 year 5 months = 29 months =29/12 years 3. Arun borrowed a sum for 4 years on S.I. at 12%. The total interest paid was Rs. 360. Find the Principal. Answer & Explanation Answer:- 4 Explanation :- P = ? R = 12% T = 4 SI =Rs. 360 4. The simple interest on Rs. 1820 from March 9, 2003 to May 21, 2003 at 7 1⁄2% rate is Answer & Explanation Answer:- 1 Explanation :- P = Rs. 1820 R = 7 1/2 = 15/2 5. At what rate percent of simple interest will a sum of money double itself in 20 years? Answer & Explanation Answer:- 2 Explanation :- Let P = x T = 20 years SI= x
SI = (500*6*73)/(100*365)
SI = Rs. 6
1. Rs.1994.25
2. Rs.1991.25
3. Rs.1992.75
4. Rs.1993.75
SI = (7500*11*29)/(100*12)
SI = 1993.75
1. Rs.700
2. Rs.650
3. Rs.800
4. Rs.750
360 = (P*12*4)/100
P = (100*360)/(12*4)
P = Rs.750
1. Rs. 27.30
2. Rs. 22.50
3. Rs. 28.80
4. Rs. 29
Total days = 22 + 30 + 21 = 73 days
T= 73/365 = 1/5 year
SI = (1820 * (15/2) * (1/5) ) / 100
SI= 27.30
1. 4%
2. 5%
3. 6%
4. 8%
R = (100 * x) / (x*20) = 5%
