# Simple Interest Questions Set 1 Solutions

**Answer 1 : C**

SI = 424 – 400 = 24

R = (24 × 100) / (400 × 3) =2%

New Rate = 2 + 8 = 10%

SI = (400 × 10 × 2) / 100 = Rs.80

Amount = 400 + 80 = Rs.480

**Answer 2 : A**

Total interest = Rs. 4425, Rate = 7% and increasing by 0.25% every year.

Let total Loan Amount = P

P= (4425× 100) / (7×1 + 7.25 × 1 + 7.5 × 1 + 7.75 × 1) = 442500 / 29.5= Rs.15000

**Answer 3 : A**

Let total sum = Rs. 100

Interest on first part = (30 × 30 × 1) / 100= Rs.9

Interest on second part = (35 × 14 × 1) / 100 = Rs.4.9

Interest on third part = (35 × 12 × 1) / 100= Rs.4.2

Total interest = 9 + 4.9 + 4.2 = 18.1

Rate of interest = 18.1%

**Answer 4 : B**

Amount invested at 15% = Rs. x

Amount invested at 20% = Rs. y

1900 = (x × 15 ×1) / 100+ (y × 20 × 1) / 100

15x + 20y = 190000 …(1)

2450 = (x × 20 × 1) / 100+ (y × 15 × 1) / 100

20x + 15y = 245000 …(2)

Solving (1) and (2), we get y = Rs. 7142.8

**Answer 5 : C**

Let first part = Rs. x , Then Second Part = 8000 – x.

Now,(x × 3 × 5) / 100 = [(8000 − x) × 5 × 9] / 100

3x / 20 = (72000 – 9x) / 20

x = Rs. 6000

Second part = 8000 – 6000 = Rs. 2000

**Answer 6 : C**

14160 = P + (P × R × 3) / 100

3PR / 100 = 14160 – P

14700 = P + (P ×1.25R × 3) / 100

P + (5/4 × 3PR / 100) = 14700

P + (5/4)(14160 − P) = 14700

4P + 70800 – 5P = 58800

P = 12000

14160 = 12000 + (12000 × R ×3) / 100

14160 = 12000 + (120 × R × 3)

14160 – 12000 = 360R

2160 = 360R

R =2160 / 360= 6%

**Answer 7 : A**

Let the two different rates be x and y respectively.

Difference between the interests is Rs 300

(5500 × x × 3) / 100 − (5500 × y × 3) / 100 = 300

16500x – 16500y = 300 × 100

16500(x – y) = 30000

x – y = 1.81%

**Answer 8 : A**

P = (SI × 100) / (R_{1}T_{1} + R_{2}T_{2} + R_{3}T_{3})

P = (21000 × 100) / (3×4 + 4×3 + 9×2) = 2100000 / (12 + 12 + 18) = Rs. 50000

**Answer 9 : C**

Difference in interests = Rs.1000

Difference in rate = 14 – 10 = 4%

Time = 5 year

In 5 year, rate of interest = 4% × 5 = 20%

20% = 1000

100% = (1000 ×100) / 20 = Rs. 5000

Total amount invested in both the schemes = 10000

**Answer 10 : B**

(7000 × R × 3) / 100 + (4000 × R × 2) / 100 = 3000

210R + 80R = 3000

290R = 3000

R=10.34%

**Answer 11 : C**

Since the second loan is given after 6 months, n = 1/2

(840 × R × 1) / 100 + (420 × 2R ×1) / (100 × 2) = 80

8.4R + 4.2R = 80

12.6R = 80

R = 80/12.6 = 6.34%

**Answer 12 : C**

Let x be the instalment

For 1^{𝑠𝑡} Year = x + (x × 8 × 1) / 100

For 2^{𝑛𝑑} Year = x + (x × 8 × 2) / 100

For 3^{rd} Year = x

[x + (x × 8 × 1) / 100] + [x + (x × 8 × 2) / 100] + x =1053

3x + 16x / 100 + 8x / 100 = 1053

300x + 24x = 105300

324x = 105300

x=325

**Answer 13 : B**

Principal = Rs.400

Amount = Rs 100 x 6 = Rs 600

Interest = Rs 600 – Rs 400 = Rs 200

Time = 6 months = 6/12 years

200= (400×1× R) / (2×100)

R = 440×100 / 400 = 100%

**Answer 14 : D**

Amount of each installment = 100P / [100n+n(n−1)R/2]

= (100 × 406) / [100×2+ 2(2−1)x3/2]

= 40600 / 203 = 200 = Rs.200

**Answer 15 : A**

Amount of each installment = 100P / [100n+n(n−1)R/2]

150 = 100 x P / [100 x 4 + 4(4−1)2/2]

150=100P / (400 + 12)

P = (150 x 412) / 100 = Rs. 618

**Answer 16 : B**

In the case of simple interest, installment amount will always be reduced from principal and the interest will be calculated on the remaining principal.

Simple interest for 1st year = PRT / 100 = (50000×5×1) / 100 = Rs. 2500

Amount after 1st installment = 50000 – 5000 = 45000

Simple interest for 2nd year = PRT / 100 = (45000×5×1) / 100 = Rs. 2250

Amount after 2nd installment = 45000 – 10000 = 35000

Simple interest for 3rd year = PRT / 100 = (35000×5×1) / 100 = Rs. 1750

Amount after 3rd installment = 35000 – 15000 = 20000

Simple interest for 4th year = PRT / 100 = (20000×5×1) / 100 = Rs. 1000

Amount after 4th installment = 20000 – 20000 = 0

Balance of debt for the 5th year = 2500 + 2250 + 1750 + 1000 = Rs. 7500

**Answer 17 : D**

Let sum be x

N = 8 yrs

SI = 900

R = (100×SI) / (P×N)

R = (100 × 900) / (x × 8) = 11250/x

For 1st 4 yrs SI = x × 11250/x × 4 × 1/100 = 450

For last 4 yrs SI = 3x × 11250/x × 4 ×1/100 = 1350

Total interest = 1350 + 450 = Rs. 1800

**Answer 18 : B**

S.I for 3 years = Rs.(1460 – 1100) = Rs.360

Sum = Rs.(1100 – 360) = Rs.740

Rate = (100 × 240) / (740 × 2) = 16.21% ≈ 16%

**Answer 19 : A**

Let each sum be Rs. P.

Then,

(P × 9 × 13) / (100 × 2) − (P × 9 × 9) / (100 × 2) = 288

117P/200 − 81P /200 = 288

36P/200 = 288

P = (288 × 200) / 36 = Rs. 1600

**Answer 20 : B**

For First loan

SI = PRT / 100 = (8000 × 1 × 9) / (100 × 2) = 360

For Second loan

SI = (12000 × 8 × 1) / 100 = 960

Total interest = 3600

So for the third loan SI = 3600 – (960 + 360) = 2280

Rate of interest for third loan = (2280 × 100) / 22000 = 10.36%
