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 sum due sometime hence is Rs. 1024 and the banker's gain is Rs.64. The true discount is:

A - 40.0%

B - 41.58%

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%

A - Rs 798

B - Rs 1050

D - None of these

Answer : C

Explanation

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 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:

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:

A - 0%

B - 5%

C - 7.5%

D - None of these

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%

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
