A. 4

B. 5

C. 6

D. 8

Show Correct Answers

A. 

Go through Option

        1 * (1.2) = 1.2

        1 * (1.2)2 = 1.44

        1 * (1.2)3 = 1.728

        1 * (1.2)4 = 2.0736

Hence minimum 4 years required to double the sum.

2. The difference between CI and SI on a sum of money lent for 2 years at 10% is Rs. 40. The sum is :

A. 1600

B. 3000

C. 4000

D. None of these

Show Correct Answers

C. 

Difference between CI and SI for 2 years = P (r/100)2

      40 = P (10/100)2 => P = 4000

3. A certain sum amounts to Rs. 8998.8 in two years and to Rs. 9528.128 in three years, at compound interest per annum. What is the principal and rate of interest?

A. Rs.12000,5%

B. Rs.6000,8%

C.Rs.8000, 6%

D. Rs.10000, 8.5%

Show Correct Answers

C.

P( 1+ r/100)3/ P( 1+ r/100)2 = (1+ r/100)

       9528.128/8988.8    =  (1+ r/100)

       ( 1 + 84270/1404500) = (1+ r/100)

       (1 + 6/100)     =  (1+ r/100)

         r = 6%

     8988.8 = P(1+ 6/100)3

       P = 8000

4. A titan watch is sold for Rs. 440 cash or for Rs. 200 cash down payment together with Rs. 244 to be paid after one month. Find the rate of interest charged in the instalment scheme :

A. 10%

B. 15%

C. 20%

D. 25%

Show Correct Answers

C

Principal for next month = 440-200 = 240

      Amount paid after next month = 244

      Therefore interest charged at Rs. 240= 4

        4 =  (240*r*1/12*100)  => r = 20% per annum

5. Purnima borrowed a sum of money and returned it in three equal quarterly instalments of Rs. 17576 each. Find the sum borrowed, if the rate of interest charged was 16% per annum compounded quarterly. Find also the total interest charged.

A. 46900 and 4700

B. 48775 and 3953

C. 68320 and 1200

D. None of these

Show Correct Answers

Rate of Interest = 16% annum

      Actual rate of Interest = 4% per Quarter

     Principal of all three installments

 

       = [ 17576 (25/26) + (25/26)2 + (25/26)3]

        =[17576*25*1951/26*676] = 48775

Total amount paid = Rs.17576 *3 = 52728

Interest charged = 52728 – 48775 = 3953

6. Sunidhi borrowed Rs. 10815, which is to be paid back in 3 equal half yearly instalments. If the interest is compounded half yearly at 40/3% per annum, how much is each instalment?

A. 2048

B. 3150

C. 4096

D. 5052

Show Correct Answers

Rate of  Interest = 40/3÷2 % = 20/3% half yearly

   10815 = x [ 15/16 + (15/16)2 + (15/16)3]

     X= 4096

A. Rs. 130

C. Rs. 120

D. Rs. 330

Show Correct Answers

(P*5*9/100*12) – (P*14*3/100*12) = 10

       P = Rs. 4000

       Now, (4000/100*12)* [5*9 + 14*3] = Rs. 290

Let the Principal be x, then

  • X=14000

10. The compound interest on a certain sum for 2 years is Rs. 756 and SI (simple interest) is Rs. 720. If the sum is invested such that the SI is Rs. 900 and the number of years is equal to the rate per cent per annum, find the rate per cent :

A. 4

B. 5

C. 6

D. 10

Show Correct Answers

CI for 2 years = Rs. 756

        SI for 2 years = Rs. 720

       It means the Interest on the  interest of the first year = Rs. 36  (756-720)

         This implies that the rate of Interest is 10% as 36/360 *100 = 10%

        It means the principal for the first year was Rs. 3600

        P*10*1/100 =360

      P= 3600

     Now,         P*k*k/100 = SI

                    3600*K2/100 = 900

                      K=5
