# 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**

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**

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**

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**

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**

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**

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
