  1. Bhanu borrowed a certain sum of money at 12% per annum for 3 years and Madhuri borrowed the same sum at 25% per annum for 10 years. Find the ratio of their amounts.

(a) 1 : 3               (b) 2 : 1               (c) 2 : 3              (d) 2 : 5

 

  1. How many times will the sum gets multiplied in 10 years at 20% per annum rate of interest?

(a) 2 times         (b) 3 times         (c) 4 times         (d) 5 times

 

  1. Suppose P1, P2 are principles, T1, T2 are time period and R1, R2 are rates of interest in two cases.

IF P1 : P2 = 2 : 3,  T1 : T2 = 3 : 5 and R1 : R2 = 5 : 8 then find the percentage with which Si in second case (I2) is more than the S.I. in I case (I1)?

(a) 100%            (b) 200%           (c) 300%            (d) 400%

 

  1. Gopi borrowed Rs. 1800 at 12% per annum for 2 years and Krishna Borrowed Rs. 1200 at 18% per annum for 3 years. Then the ratio of interests paid by them is

(a) 1 : 2               (b) 2 : 3              (c) 3 : 1               (d) 2 : 1

 

  1. What is the difference in SI if a sum of Rs. 4000 is borrowed by a person for 4 years and the rate of interest is increased from 4% to 5%?

(a) Rs. 180        (b) Rs. 160        (c) Rs. 140         (d) Rs. 120

 

  1. A and B borrowed Rs. 4500 and Rs. 5000 respectively at the same rate of interest for 3½ years. If B paid Rs. 280 more interest than A. Then the rate of interest per annum is

(a) 12%               (b) 14%               (c) 15%               (d) 18%

 

  1. Divide Rs. 8000 into two parts so that the SI on the first part for 5 years at 12% per annum is equal to SI on the second part for 2 years at 18% per annum.

(a) 2000, 6000                             (b) 5000, 3000

(c) 4000, 4000                             (d) None

(a) Rs. 9260      (b) Rs. 7240      (c) Rs. 9240      (d) Rs. 8240

 

  1. A sum of Rs. 450 amounts to Rs. 495 in 2 years. In what time will the Sum of Rs. 820 amount to Rs. 943 at the same rate?

(a) 3 years         (b) 2 years         (c) 4 years         (d) 6 years

 

  1. In how many years does a certain sum amount to three times the principle at the rate of ?

(a) 12 years       (b) 8 years         (c) 4 years         (d) 16 years

 

  1. Find the SI on Rs. 1800 first 21st Feb 2003 to 12th April 2003 at 7.3% rate per annum.

(a) Rs. 18.25     (b) Rs. 18.00    (c) Rs. 18.50     (d) Rs. 18.75
