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. 5124 due 2 months hence is Rs. 244. The rate percent is:
Answer : D
Explanation
Present worth = Rs. (5124 - 244) = Rs. 4880. S.I. on Rs. 4880 for 2 months is Rs. 244. R=( 100*TD)/PW*T=( 100*244)/(4880*(2/12)) =30%
Q 3 - The present worth of a sum due sometime hence is Rs. 1024 and the banker's gain is Rs.64. The true discount is:
Answer : A
Explanation
T.D. = √(P.W.x B.G.) =√(1024x64.) =Rs. 256
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:
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 - Find a single discount which is equivalent to three successive discounts of 15%, 16% & 20%.
Answer : C
Explanation
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 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 - 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:
Answer : A
Explanation
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.
