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 banker's gain on a bill due 3 year hence at 6% per annum is Rs. 18. The true discount is:

A - Rs.100

B - Rs.75

A - Rs.6

B - Rs.6.4

C - Rs.6.5

D - Rs. 6.75

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

A - 5%

B - 6%

C - 7%

D - 8%

Answer : A

Explanation

P.W. = Rs (5125-125) = Rs 5000
S.I. on Rs 5000 for 1/2 year is Rs 125
∴ R = (100*125)/(5000*1/2)% p.a. = 5% p.a.

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

Explanation

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%

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.
