1. The banker's gain on a sum due 3 years hence at 12% per annum is Rs. 270. The banker's discount is:
Answer: Option C
Explanation:Let Amount=X
Banker's Gain (B.G) = Banker's Discount (B.D) - True Discount (T.D)
270 = (X*12*3)/100 - (X*12*3)/(100 (12*3))
X=2833.33
B.D=2833.33*12*3/100
B.D=1020
So Option C is correct

4. The banker's discount on Rs. 1600 at 15% per annum is the same as true discount on Rs. 1680 for the same time and at the same rate. The time is:
Answer: Option B
Explanation:S.I on Rs. 1600= T.D on Rs. 1680.
So, Rs. 1600 is the present worth of Rs. 1680; i.e; Rs. 80 is on Rs. 1600 at 15%.
So, time=(100*80)/(1600*15)
= 1/3 years
= 4 months.

5. The banker's gain of a certain sum due 2 years hence at 10% per annum is Rs. 24. The present worth is:
Answer: Option C
Explanation:T.D= (B.G*100)/(R*T)

So, present worth P.W= (100*T.D)/(R*T)
= Rs. (100*120)/(10*2)
= Rs. 600
