Correct Answers

  1. Option – D

let the sum be P.

CI = P(1 + 20/100)2  – P = 770

=> 1.44P – P = 770

=> 0.44P = 770

=> P = 1750

Now rate of interest = 1% pm = 12% p.a.

SI =  1750 × 12 × 3 / 1000 = 630

 

  1. Option- D

Let the sum be x.

When compounded annually,

Amount = x(1+10/100)

2 =121x/100

When compounded half-yearly,

Amount = x(1+5/100)

4 =194481x/160000

Now,

194481x/160000 -121x/100 =440.5

=> 881x/160000 = 440.5

= x= 80000

 

  1. Option – B

(SI)1 – (SI)2 = (PT)/100 x (R1 – R2)

96 = (P x 5/100) x (3)

So, P = 640

 

  1. Option –B

Let the sum be P and annual interest be I.

From the 1

st condition, P + 3I = 2365 … (1)

According to the 2

nd condition, P + 5I = 2655 … (2)

On solving the equations we get, P = Rs 1930 and I = Rs 145

 R = 145 × 100/1930 =  7.5% ( Approx)

 

  1. Option- A

R =  ( SI × 100/ ( P × T) = 6800× 100 / (17000 × 4)  = 10%

CI = P ( 1 + R /100)T – P

     = 17000{ ( 1.1)4 – 1 }

    = 17000 × 1.464 – 1) = 7889.7

 

  1. Option – A

As we know that amount of simple interest that we get in each year remains same.

So let’s assume Principal Amount invested is Rs P and interest of one year is Rs A.

Hence according to the 1

st condition, P + 3A = 5000 .. (1)

Similarly, P + 5A = 5450 .. (2)

From both the equations we will get,

P = Rs 4325 and A = Rs 225

So, R = 225/4325 × 100 = 5.2%

 

  1. Option – A

Let Principal = P

Compound interest at 20% per annum for 2 years = P(1+20/100)2– P = 44% of P = 880

P = 2000

Now SI for 4 years  @ 10 % =  40% of 2000 = 800

 

  1. Option – B

P = Rs 20000; R = 15% p.a. = 7.5 % per half-year;

T = 1 year = 2 half-years

If an amount P is compounded at interest rate of r for T years then the total amount which we Will get = P (1 + r/100)T

Amount = Rs.[20000 X (1 +7.5/100) X (1 +7.5/100)]

=  23112.5

 

  1. Option – C

Let’s assume interest rate = R%

Total interest paid by Vinod = Rs (6000 + 8000 – 10000)

= Rs 4000

Now total interest paid = Interest on Rs 10000 for 4 years + Interest on Rs 4000 (10000 – 6000) for 2 years

=> 4000 = (10000 X 4 X R)/100+(4000 X 2 X R)/100

=>4000 = 400R + 80R

480R = 4000 

R = 8  1/3 %

 

  1. Option- C

As we know that when an amount P is invested for two years at rate of R% per annum then the difference between SI and Ci = PR2/100

Overall gain = 3000 × 0.12)2  = 432
