Given that BG = ₹ 144 , R = 24%
T = 8 yr and PW = ?
According to the formula,
PW = BG x [100/(R x T)]^{2}
= 144 x [100/(24 x 8)]^{2}Correct Option: A
Given that BG = ₹ 144 , R = 24%
T = 8 yr and PW = ?
According to the formula,
PW = BG x [100/(R x T)]^{2}
= 144 x [100/(24 x 8)]^{2}
= 144 x (100/192) x (100/192)
= ₹ 39.06

Given that, BD = ₹ 196 and BG = ₹ 28
∴ TD = BD  BG = 196  28 = ₹ 168
According to the formula,
A = (BD x TD)/BG = (196 x 168)/28Correct Option: C
Given that, BD = ₹ 196 and BG = ₹ 28
∴ TD = BD  BG = 196  28 = ₹ 168
According to the formula,
A = (BD x TD)/BG = (196 x 168)/28
= 196 X 6
= ₹ 1176

T.D. = (90 x 100) / (3 x 5) = Rs. 600
∴ Banker's discount = True discount + Banker's gainCorrect Option: C
T.D. = (90 x 100) / (3 x 5) = Rs. 600
∴ Banker's discount = True discount + Banker's gain
= Rs. 600 + Rs. 90
= Rs. 690
