The true discount on a certain sum due 1 yr hence at 30% per annum, is ₹ 240. What is the banker' discount on the same sum for the same time and at the same rate?
Correct Answer: ₹ 312
Explanation:
We know that
BG = SI on TD = (240 x 30 x 1 x 1)/100
= ₹ 72
BG = BD - TD
⇒ BD = BG + TD
= 72 + 240
= ₹ 312
