Given that PW = ₹ 576 , BG = ₹ 9 and TD = ?
TD = PW x BG

Correct Option: D

Given that PW = ₹ 576 , BG = ₹ 9 and TD = ?
TD = PW x BG
= 576 x 9
= 24 x 3
= ₹ 72

Given that, PW = ₹ 2200, TD = ₹ 220
According to the formula,
BG = (TD)²/PW

Correct Option: A

Given that, PW = ₹ 2200, TD = ₹ 220
According to the formula,
BG = (TD)²/PW = (220 x 220)/2200 = ₹ 22
BD = (TD + BG) = ₹(220 + 22) = ₹ 242

Given that, R = 24%, T = 24 months= 2 yr and TD = ₹ 144
BD = TD + BG
According to the formula,
BG = (TD x R x T)/100 = (144 x 24 x 2)/100

Correct Option: D

Given that, R = 24%, T = 24 months= 2 yr and TD = ₹ 144
BD = TD + BG
According to the formula,
BG = (TD x R x T)/100 = (144 x 24 x 2)/100
= ₹ 69.12
∴ BD = 144 + 69.12 = ₹ 213.12

Give that A = ₹ 13800 , R = 5%
T = 5 yr and BG = ?
According to the formula,
BG = [A(R x T)²] / [100(100 + R x T)]

Correct Option: A

Give that A = ₹ 13800 , R = 5%
T = 5 yr and BG = ?
According to the formula,
BG = [A(R x T)²] / [100(100 + R x T)]
= [13800(5 x 5)²] / [100(100 + 5 x 5)]
= (13800 x 625) / (100 x 125)
= ₹ 690

B.D. for 3/2 years = Rs. 60
B.D. for 2 years = Rs. (60 x 2) / (3 x 2) = Rs. 80
Now, B.D. = Rs. 80, T.D. = Rs. 75 and Time = 2 years.
∴ Sum = Rs. (80 x 75) / 5 = Rs. 1200
∴ Rs. 80 is S.I. Rs. 1200 for 2 years.

Correct Option: D

B.D. for 3/2 years = Rs. 60
B.D. for 2 years = Rs. (60 x 2) / (3 x 2) = Rs. 80
Now, B.D. = Rs. 80, T.D. = Rs. 75 and Time = 2 years.
∴ Sum = Rs. (80 x 75) / 5 = Rs. 1200
∴ Rs. 80 is S.I. Rs. 1200 for 2 years.
So, rate = (100 x 80) / (1200 x 2)% = 3¹/₃%
