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 - The true discount on Rs. 3520 due after a certain time at 18% per annum is Rs. 320. The time after which it is due is:

Answer : C

Explanation

P.W. = Rs. (3520 -320) = Rs. 3200.
S.I. on Rs. 3200 at 18% is Rs. 320.
Time = ( 100*TD)/PW*R=  ( 100*320)/3200*18= 5/9 years

Q 3 - The banker's gain on a bill due 3 year hence at 6% per annum is Rs. 18. The true discount is:

Answer : A

Explanation

T.D=(B.G * 100)/( R * T)
= 18 * 100/( 6 * 3)
= Rs. 100

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 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 genuine rebate on Rs 5125 due 6 months subsequently is Rs 125. The rate of interest per annum is:

Answer : A

Explanation

P.W. = Rs (5125-125) = Rs 5000
S.I. on Rs 5000 for 1/2 year is Rs 125
∴ R = (100*125)/(5000*1/2)% p.a. = 5% p.a.

Q 7 - The basic hobby and the true rebate on a sure aggregate for a given time and at a given rate are Rs 85 and Rs 80 separately. The entirety due is:

Answer : A

Explanation

Sum due = ((S.I.)*(T.D.))/((S.I.)-(T.D.))=Rs ((85*80))/((85-80))=((85*80))/5= Rs 1360

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 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
