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 - 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 - 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 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 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 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?
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 - On the off chance that Rs 10 be permitted as genuine rebate on a bill of Rs 110 due toward the end of a sure time, then the markdown permitted on the same total due toward the end of twofold the time is:
Answer : C
Explanation
S.I. on Rs (110-10) for a fixed time = Rs. 10 S.I. on Rs. 100 for double the time Rs. = 20 T.D. on Rs 120- Rs 20 T.D. on Rs 110 = Rs (20/120*100) = Rs 55/3 = Rs. 18.33
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.
