Q 1 - Find the single discount which is equivalent to successive discounts of 15% and 16%. 
A - 36.6%
B - 31%
C - 28.6%
D - 28.6%
Successive discount is calculated as X+Y-XY/100 %
Successive discount =15+16-15*16/100=31-240/100=28.6 %
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
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
(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
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 - Find a single discount which is equivalent to three successive discounts of 15%, 16% & 20%.
A - 40.0%
B - 41.58%
C - 42.88%
D - 43.76%
Successive discount is calculated as X+Y-XY/100 %
Successive discount =15+16-15*16/100=31- 240/100=28.6 %
Successive discount =28.6+20-28.6*20/100=48.6-5.72=42.88%
Q 6 - The genuine markdown on an aggregate due 3 years consequently at 8% p.a. is Rs 252. The total due is:
A - Rs 798
B - Rs 1050
C - Rs 1302
D - None of these 
P.W. = (100*T.D.)/(R*T) = Rs ((100*252))/((8*3)) = Rs 1050
Sum due = (P.W.)+(T.D.) = Rs (1050+252) = Rs 1302
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%
((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 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 
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 - In the event that Rs 20 be permitted as genuine rebate on a bill of Rs 260 due after at some point, what will be the genuine markdown on the same bill for half of the time?
A - Rs 10
B - Rs 10.40
C - Rs 13
D - Rs 15.20
S.I. on Rs (260-20) for a fixed time = Rs 20
S.I. on Rs 240 for half the time = Rs 10
T.D. on Rs 250 = Rs 10
T.D. on Rs 260 = Rs (10/250*260) = Rs 10.40
Q 10 - The basic enthusiasm on Rs 750 for a long time is equivalent to the genuine rebate on Rs 810 for the same time and at the same rate. The rate of interest per annum is:
A - 4%
B - 13/3%
C - 5%
D - 31/6%
S.I. on Rs 750 for 2 years = T.D. on Rs 810 due 2 years hence
∴ P.W. of Rs. 810 due 2 years hence = Rs 750
∴ T.D. = Rs (810-750) = Rs 60
Rate = ((100*60)/(750*2))% p.a. = 4% p.a.
