SI and CI Questions Set 1 Solutions
Answer 1 : C
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 101.50, R = 3%, SI = ?, then
101.50 = SI(1 + 3/200)
101.50 = SI(203/200)
SI = (101.50 x 200) / 203
SI = Rs. 100
Answer 2 : B
P = ?, CI = 252.20, R = 5%, n = 3 years
CI = P[(1 + R/100)^n – 1]
252.20 = P[(1 + 5/100)^3 – 1]
252.20 = P[(1 + 1/20)^3 – 1]
252.20 = P[(21/20)^3 – 1]
252.20 = P[(9261/8000) – 1]
252.20 = P x (1261/8000)
P = (252.20 x 8000) / 1261
P = 1600
Thus,
SI = PRT / 100
SI = (1600 x 5 x 3) / 100
SI = Rs. 240
Answer 3 : C
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then
CI = SI(1 + R/200)
Since CI = 282.15, R = ?, SI = 270, then
282.15 = 270(1 + R/200)
282.15 / 270 = (1 + R/200)
(282.15 / 270) – 1 = R/200
12.15 / 270 = R/200
R = (12.15 x 200) / 270
R = 9%
Answer 4 : B
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 510, R = 12 1/2% = 25/2%, SI = ?, then
510 = SI(1 + 25/400)
510 = SI x 425/400
SI = (510 x 400) / 425
SI = Rs. 480
Answer 5 : C
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 40.80, R = ?, SI = 40, then
40.80 = 40(1 + R/200)
40.80/40 = 1 + R/200
4080/4000 = 1 + R/200
408/400 = (200 + R)/200
(408/400) x 200 = 200 + R
204 = 200 + R
R = 4% per annum
Answer 6 : A
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 328, R = 5%, SI = ?, then
328 = SI(1 + 5/200)
328 = SI(1 + 1/40)
328 = SI(41/40)
SI = (328 x 40) / 41
SI = Rs. 320
Answer 7 : B
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 2448, R = 4%, SI = ?, then
2448 = SI(1 + 4/200)
2448 = SI(204/200)
SI = (2448 x 200) / 204
SI = Rs. 2400
Answer 8 : C
SI = PRT/100 = PR x 1/100 = 260,
Thus PR = 26000
Now, CI = 540.80, n = 2 years
540.80 = P[(1 + R/100)^2 – 1]
540.80 = P[1 + (R/100)^2 + 2(R/100) – 1]
540.80 = P[(R/100)^2 + 2(R/100)]
540.80 = (PR)R/10000 + 2(PR/100)
Since PR = 26000
540.80 = 26000R/10000 + 2(26000/100)
540.80 = 26R/10 + 520
540.80 – 520 = 26R/10
20.80 x 10 = 26R
R = 208/26 = 8%
Answer 9 : D
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = ?, R = 4%, SI = 80, then
CI = 80(1 + 4/200)
CI = 80(1 + 1/50)
CI = (80 x 51) / 50
CI = Rs. 81.60
Answer 10 : D
P = ?, CI = 246, R = 5%, n = 2 years
CI = P[(1 + R/100)^n – 1]
246 = P[(1 + 5/100)^2 – 1]
246 = P[(1 + 1/20)^2 – 1]
246 = P[(21/20)^2 – 1]
246 = P[(441/400) – 1]
246 = P x (41/400)
P = (246 x 400) / 41
P = 2400
Thus,
SI = PRT / 100
SI = (2400 x 6 x 3) / 100
SI = Rs. 432
Answer 11 : D
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 954, R = ?, SI = 900, then
954 = 900(1 + R/200)
954/900 = 1 + R/200
954/900 – 1 = R/200
54/900 = R/200
R = 12%
Thus,
SI = PRT / 100
900 = (P x 12 x 2) / 100
P = Rs. 3750
Answer 12 : D
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 420, R = 10%, SI = ?, then
420 = SI(1 + 10/200)
420 = SI(1 + 1/20)
420 = SI(21/20)
SI = (420 x 20) / 21
SI = Rs. 400
Answer 13 : D
P = ?, CI = 102, R = 4%, n = 2 years
CI = P[(1 + R/100)^n – 1]
102 = P[(1 + 4/100)^2 – 1]
102 = P[(1 + 1/25)^2 – 1]
102 = P[(26/25)^2 – 1]
102 = P[(676/625) – 1]
102 = P x (51/625)
P = (102 x 625) / 21
P = 1250
Thus,
SI = PRT / 100
SI = (1250 x 2 x 4) / 100
SI = Rs. 100
Answer 14 : D
P = 100, SI = 100, R = ?, n = 8 years
SI = PRT / 100
100 = (100 x R x 8) / 100
R = 100 / 8 = 25/2%
Now, P = 8000, CI = ?, R = 25/2, n = 2 years
CI = P[(1 + R/100)^n – 1]
CI = 8000[(1 + 25/200)^2 – 1]
CI = 8000[(1 + 1/8)^2 – 1]
CI = 8000[(9/8)^2 – 1]
CI = 8000[(81/64) – 1]
CI = 8000 x 17 / 64
CI = Rs. 2125
Answer 15 : A
The simple interest for a certain sum for 2 years at an annual rate interest R% is SI, then the compound interest is
CI = SI(1 + R/200)
Since CI = 2544, R = 12%, SI = ?, then
2544 = SI(1 + 12/200)
2544 = SI(212/200)
SI = (2544 x 200) / 212
SI = Rs. 2400
