If the true discount on a certain sum due 6 months hence at 20% is Rs. 140, what is the banker’s discount on the same sum for the same time and at the same rate?
Rs.248
Rs.148
Rs.124
Rs.154
Explanation:
B.G. = S.I. on T.D.
on Rs. ($140 \times 20 \times \dfrac{1}{2} \times \dfrac{ 1}{100}$)
= Rs. 14
Therefore, B.G. – T.D. = Rs. 14
B.G. = Rs. (140 + 14)
=Rs. 154.
