Amount = Rs. 1860.
True discount = Rs. 60
∴ Present worth = Rs. 1860  Rs. 60 = Rs. 1800
S.I. on Rs. 1800 for 8 months = Rs. 60Correct Option: A
Amount = Rs. 1860.
True discount = Rs. 60
∴ Present worth = Rs. 1860  Rs. 60 = Rs. 1800
S.I. on Rs. 1800 for 8 months = Rs. 60
∴ Rate = [(100 x 60) / (1800 x 2/3)]% = 5%
∴ Banker's discount = (1860 x 5 x 2/3)/100 = Rs. 62

Given That, A = ₹ 12750, R = 6%
and T = 4 Months = 4/12 = 1/3 yr , BD = ?
According to the formula,
BD = (A x R x T)/100Correct Option: C
Given That, A = ₹ 12750, R = 6%
and T = 4 Months = 4/12 = 1/3 yr , BD = ?
According to the formula,
BD = (A x R x T)/100

= (12750 x 2) / 100
= ₹ 255

Present worth of bill = ₹ (7440  240) = ₹ 7200
∴ Banker's Gain (BG) = (TD)^{2}/PW
= (240 x 240) / 7200Correct Option: D
Present worth of bill = ₹ (7440  240) = ₹ 7200
∴ Banker's Gain (BG) = (TD)^{2}/PW
= (240 x 240) / 7200
= 576/72
= ₹ 8
