Answers :

1) Answer: D

Let the invested amount be Rs.P

D = [Pr2 (300+r)] / 1003

4394.25 = P*152 * (300+15) / 1000000

P= Rs.62000

Simple interest = 62000 * 2 * 15/100 = Rs.18600


2) Answer: D

SI received by Kanish = 8000 * R * 3/100 = 240R

SI received by Kanika = 7500 * (R + 5) * 2/100 = 150R + 750

240R/(150R + 750) = 6/5

200R = 150R + 750

R = 15%


3) Answer: C

11109 = x * (1 + 15/100)2

11109 = x * 23/20 * 23/20

x = Rs.8400

6048 = 8400 * R * 4/100

R = 18%


4) Answer: D

Let the amount invested in bank B = x

The amount invested in Bank A = 7500 – x

(7500-x)*3*12/100 + x*3*15/100 = 3105

x= 4500


5) Answer: B

8000*R1*3/100-8000*R2*3/100=1200

80*3(R1-R2) =1200

R1-R2=5%


6) Answer: D

The difference between the simple interest and compound interest for 3 years is,

Difference = [Sum* r2 * (r + 300)]/1003

1123.2 = [Sum*144*312]/1003

Sum = (1123.2*100*100*100)/(144*312)

Sum = Rs. 25000


7) Answer: B

SI = 3422 – 2900 = 522

Rate = SI * 100/(P * time) = 522 * 100/(2900 * 3) = 6%

New rate = 6 + 3 = 9%

New SI = 2900 * 9 * 3/100 = Rs. 783

Amount = P + SI = 2900 + 783 = 3683


8) Answer: C

SI=P * N * R/100

x * 15 * 8/100 – x * 12 * 8/100=4800

24x=480000

x=20000


9) Answer: A

According to the question,

6800*((x+100)/100)((x+100)/100) – 6800 = 1428

6800*((x+100)/100)((x+100)/100) = 8228

68 * (x+100)²/100 = 8228

(x+100)² = 12100

x+100 = 110

x= 10

For SI, R = 10+5 = 15 %

SI = 6800 * 15 * 3/100=Rs. 3060


10) Answer: E

SI=P * N * R/100

400/100 * 4800=4800 * 8 * x/100

x =50%

Answers :

11) Answer: C

SI = P * N * R/100

CA = P * (1 + R/100)n

Amount earning simple interest = P + P * 20 * 5/100 = 2P

7935 = 2P * (1 + 15/100)2

7935 = 2P * 1.3225

P = 3000


12) Answer: A

Difference between interests = Rs.3200

(2P-4000)[(1+(20/100))2-1] – ((P+2000)*2×20)/100 =3200

(2P-4000)(11/25) – (10(P+2000))/25 =3200

P=Rs.12000


13) Answer: C

Ratio of amount invested in A and B = 4:3

Amount invested in A = 4/7 x 56000 = 32000

Amount invested in Scheme B = 3/7 x 56000 = 24000

Total interest earned = 32000 x 8% x 4 + 24000 x 10% x 4 = 10240 + 9600 = Rs. 19840


14) Answer: A

Amount invested by Aman = Rs. 1440

And he gets after 2 years = Rs. 2560

Then, according to the question,

2560 = 1440 × (1 + R/100)2

256/144 = (1 + R/100)2

4/3 = (100 + R)/100

400 = 300 + 3R

R = 33 1/3%

So, the simple interest earned by Aman is,

= 3500 × 100/3 × 6/100

= Rs. 7000


15) Answer: A

Difference=Pr2/(100)2

5.88=1200* r2/100*100

5.88*10000/1200= r2

r2=49

r=7%


16) Answer: A

Interest received by Anju = 24000 * ((1 + 0.15)3 – 1)

= Rs.12501


17) Answer: B

Let amount invested in 1st scheme be x,

Amount invested in 2nd scheme be 52000-x

It is given that,

x=Rs.36000

Therefore amount invested in 2nd scheme = 52000-36000 = Rs.16000


18) Answer: E                                                       

Difference = (25000 * 20 * 20)/(100 * 100)

= Rs.1000


19) Answer: B

Given that, SI = Rs.500, n = 2 years and P = Rs.5000

SI = Pnr/100

r = (100 * SI)/(P * n)

= (100 * 500)/(5000 * 2)

= 5%


20) Answer: B

CA = P * (1 + r/100)n

11750.4 = x * (1 + 20/100)3

x = 6800
