Questions and Answers

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:

A - 375

B - 400

C - 430

D - 480

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?

A - Rs. 19.66

B - Rs. 20.66

C - Rs. 21.66

D - Rs. 22.66

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:

A - 41

B - 50

C - 51

D - 41.6

Answer : A

Explanation

(T.D.)2 = P.W. * B.G
=>  B.G=(T.D.)2/
P.W.=402/1600=1
=>B.D =T.D. + B.G. 
= 40+1 
=41

Q 4 - A man buys a watch for Rs. 2825 in cash and sells it for Rs. 3300 at a credit of 1 year. If the rate of interest is 15% per annum, the man:

A - Rs. 150

B - Rs. 175.

C - Rs. 475

D - Rs. 500

Answer : B

Explanation

S.P. = P.W. of Rs. 3300 due 1 year hence = 3300*100/( 100+(10*1))=Rs.3000
So Gain = Rs. (3000-2825) =Rs. 175.

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

A - Rs.6

B - Rs.6.4

C - Rs.6.5

D - Rs. 6.75

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:

A - Rs 2464

B - Rs 2500

C - Rs 3360

D - Rs 3100

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 genuine rebate on Rs 2580 due after some time at 6% p.a. is Rs 180. After what amount of time is the aggregate due?

A - 5 months

B - 4 months

C - 1 year 3 months

D - 1 year 4 months

Answer : C

Explanation

P.W. = Rs (2580-180) = Rs. 2400
S.I. on Rs 2400 at 6% p.a. is Rs. 180
∴ Time = ((100*180))/((2400*6)) years =5/4 years = 1 year 3 months.

Q 8 - A man acquired a look for Rs 1950 in real money and sold it for Rs 2160 at a credit of 1 year. On the off chance that the rate of hobby is 8% p.a., then the man has:

A - an increase of Rs 210

B - a addition of Rs 50

C - an addition of Rs 60

D - lost Rs 30

Answer : B

Explanation

C.P. = Rs. 1950
S.P. = P.W. of Rs. 2160 due 1 year hence
= Rs ((100*2160))/(100+(8*1)) = Rs 2000 in cash.
∴ Gain = Rs (2000-1950) = Rs 50

Q 9 - I purchased a bike for Rs 1056 in real money and sold it around the same time for Rs 1296 payable following 6 months. On the off chance that the rate of hobby is 12% p.a., what amount was my addition?

A - 11.1%

B - 12.25%

C - 13.6%

D - 22.7%

Answer : C

Explanation

C.P.  = Rs 1056
S.P. = P.W. of Rs 1296 due 6 months hence
= Rs. (100*1296)/(100+(12*1/2) ) = Rs ((100*1296))/106= 1200
∴ Profit = Rs (1200-1056) = Rs 144
Gain% = (144/1056*100)% = 13.6%

Q 10 - A businessperson needs to pay to a wholesaler a total of Rs 10028 following 1 year. He needs to pay the obligation following 3 months. On the off chance that the rate of hobby is 12% p.a., the amount he will need to pay?

A - Rs 9200

B - Rs 9600

C - Rs 9560

D - Rs 9025.20

Answer : A

Explanation

Payment to be made = P.W. of Rs. 10028 due 9 months hence
= Rs ((100*10028))/(100+(12*3/4) )= Rs ((100*10028))/109= Rs 9200
