A - 375

B - 400

C - 430

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 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

Answer : A

Explanation

(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

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.

A - 40.0%

B - 41.58%

C - 42.88%

D - 43.76%

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 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

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 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?

A - 5 months

B - 4 months

C - 1 year 3 months

D - 1 year 4 months

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 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

Answer : B

Explanation

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 - 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?

A - 11.1%

B - 12.25%

C - 13.6%

D - 22.7%

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 - 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
