Q 1 - A shopkeeper professes to sell all things at a discount of 20% ,but increases selling price of each article by 30% .His gain on each article is

Answer : B

Explanation

Let us assume cost price is 100.Then the marked price is 130
SP=130 * 80/100= 104.
Profit % =(S.P-C.P)/(C.P) * 100=(104-100)/100 * 100 
=4%

Q 2 - The true discount on a bill due 6 months hence at 8% per annum is Rs. 296. The amount of the bill is:

Answer : A

Explanation

Let P.W. be Rs. X.
Then, S.I. on Rs. X at 8% for 6 months = Rs. 296.
X*8* (6/12) * (1/100) =296
X= (296*100)/4=7400
P.W. = Rs. 7400.

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.=40²/1600=1
=>B.D =T.D. + B.G. 
= 40+1 
=41

Q 4 - The banker's gain of a certain sum due 3 years hence at 20% per annum is Rs. 48. The present worth is:

Answer : D

Explanation

T.D. =(B.G*100)/( R*T)=48*100/( 20*3)=Rs. 80.
Present worth=( 100*TD)/R*T=( 100*80)/20*3=Rs.133.33

Q 5 - The banker's discount on a sum of money for 2.5 years is Rs. 1125 and the true discount on the same sum for 2 years is Rs.800. The rate percent is:

Answer : A

Explanation

B.D. for 2.5(5/2) years = Rs. 1125.
B.D. for 2 years = Rs. (1125*( 2)/5*2) =Rs. 900.
T.D. for 2 years = Rs. 800.
Sum =( B.D*T.D )/(B.D*-T.D)=Rs.( ( 900*800 )/(900-800))=Rs. 900*800/100=Rs. 7200
Thus, Rs. 900 is SI on Rs. 7200 for 2 years
Rate = ( 100*900 )/7200*2=6.25%

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 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?

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 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 - 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?

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?

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
