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 - 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:

A - 9/4 years

B - 6/5 years

C - 5/9 years

D - 4/9 years

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:

A - Rs.100

B - Rs.75

C - Rs.50

D - Rs.33.33

Answer : A

Explanation

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

Q 4 - The true discount on a bill of Rs. 360 is Rs. 60. The banker's discount is:

A - Rs.72

B - Rs.36

C - Rs.18

D - Rs.6

Answer : A

Explanation

P.W.=Rs.(360-60)=Rs.300
SI on Rs.300 =Rs.60
SI on Rs.360 =Rs. (60/300) * 360=Rs.72
B.D. = Rs.72

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:

A - 6.25%

B - 6 %

C - 5.25%

D - 5%

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 genuine markdown on an aggregate due 8 months consequently at 6% p.a. is Rs 130. The total due is:

A - Rs 3120

B - Rs 3250

C - Rs 3380

D - None of these

Answer : C

Explanation

P.W. = Rs (100*130)/(6*8/12) = Rs 3250
Sum due = (P.W.) + (T.D.) = Rs (3250+130) = Rs 3380

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:

A - 8%

B - 17/2%

C - 35/4%

D - 25/3%

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 needs to offer his old bike. He has two clients. One of them needs to pay Rs 12000 in trade and the other out Rs 13500 payable following 8 months. On the off chance that the rate of hobby is 12% for every annum, which alternative is better for the dealer?

A - Rs 12000 in real money

B - Rs 13500 payable following 8 months

C - both are just as great

D - None of the above

Answer : B

Explanation

Cash payment = Rs 12000
P.W. of Rs. 13500 payable after 8 months = Rs ((100*3500))/(100+(12*8/12) )
= Rs ((100*13500))/108=Rs 12500
∴ Rs 13500 payable after 8 months is a better offer

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?

A - 12%

B - 14%

C - 15%

D - 50/3%

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?

A - A, Rs 28.50

B - B, Rs 37.50

C - A, Rs 50

D - B, Rs 50

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
