Q 1 - The true discount and the simple interest on a certain sum for a given time and at a given rate are Rs. 240 and Rs. 160 respectively. The sum is:

### Answer : D

### Explanation

Sum =( S.I * T.D )/(S.I - T.D)=( 240 * 160 )/(240-160)=480

Q 2 - Rs. 40 is the true discount on Rs. 520 due after a certain time. What will be the true discount on the same sum due after half of the former time, the rate of interest being the same?

### Answer : C

### Explanation

S.I. on Rs. (520 - 40) for a given time = Rs. 40. S.I. on Rs. 480 for half the time = Rs. 20. T.D. on Rs. 500 = Rs. 20 T.D. on Rs. 520 =Rs. ( 20/480 * 520)= Rs. 21.66

Q 3 - The present worth of a certain bill due sometime hence is Rs. 1600 and the true discount is Rs. 40. The banker's discount is:

### Answer : A

### Explanation

(T.D.)^{2}= P.W. * B.G => B.G=(T.D.)^{2}/ P.W.=40^{2}/1600=1 =>B.D =T.D. + B.G. = 40+1 =41

Q 4 - Ramesh has to pay Rs. 440 to Suresh after 1 year. Suresh asks Ramesh to pay Rs. 220 in cash and defer the payment of Rs. 220 for 2 years. Ramesh agrees to it. If the rate of interest be 10% per annum, in this mode of payment:

### Answer : A

### Explanation

Ramesh has to pay = Present worth of Rs. 440 due 1 year hence =Rs. 440 * 100/( 100+(10*1))=Rs. 400. Ramesh actually pays = Rs. 220 + Present worth of Rs. 220 due 2 year hence =220+220*100/( 100+(10*2))=403.33 So Ramesh Loss = Rs. (400-403.33) = Rs. 3.33

Q 5 - The difference between a discount of 20% on Rs. 1000 and two successive discounts of 16% and 4% on the same amount is

### Answer : B

### Explanation

First discount of 20% on 1000=Rs. 200 Second discount = (16% of 1000)+(4% of 84% of 1000) = (160) + ( 4/100 x 84/100 *1000) =Rs. 193.6 Difference=Rs. (200-193.6) =Rs.6.4.

Q 6 - The present worth of Rs 2800 due 2 years henceforth at 6% p.a. is:

### Answer : B

### Explanation

P.W. = ((100*A))/(100+(R*T))- Rs {(100*2800)/(100+(6*2))} =Rs ((100*2800)/112)=Rs 2500

Q 7 - The straightforward hobby and the genuine rebate on a sure total due 6 months subsequently are Rs 25 and Rs 24 individually. The rate of interest per annum is:

### Answer : D

### Explanation

((S.I.)*(T.D.))/((S.I.)-(T.D.))=Rs ((25*24))/((25-24))= Rs 600 S.I. on Rs 600 for 6 months is Rs 25 ∴ Rate = (100*125)/(600*6/12)% p.a. = 25/3% p.a.

Q 8 - A man bought dairy animals for Rs 3000 in real money and sold it that day for Rs 3660 due 2 years consequently. In the event that the rate of hobby is 10% p.a., the man picks up:

### Answer : D

### Explanation

C.P. = Rs 3000 S.P. = P.W. of Rs 3660 due years hence = Rs ((100*3660))/(100+(10*2))=Rs ((100*3660))/120 = Rs 3050 ∴ Gain% = (50/3000*100)% = 5/3%

Q 9 - The genuine markdown on Rs 960 due 2 years thus is equivalent to the basic enthusiasm on Rs 750 for a long time. What is the rate of interest per annum?

### Answer : B

### Explanation

S.I. on Rs 750 for 2 years = T.D. on Rs 960 due 2 years hence ∴ P.W. of Rs. 960 due 2 years hence = Rs 750 ∴ T.D. = Rs (960-750) = Rs 210 ∴ Rate = ((100*210))/((750*2))% p.a. = 14% p.a.

Q 10 - A needs to pay Rs 1573 to B following 11/2 years and B needs to pay Rs 1444.50 to A following 6 months. In the event that the rate of hobby is 14% for each annum and both need to settle the record at this time, who will pay to the next and what amount?

### Answer : D

### Explanation

P.W. of loan on A = Rs ((100*1573))/(100+(14*2/3) )= Rs ((100*1573))/121= Rs 1300 P.W. of loan on B = Rs ((100*1444.50))/(100+(14*1/2) )= Rs ((144450))/103= Rs 1350 So, B will pay Rs. 50
