B.G. = (T.D.)2 / P.W. = Rs. (36 x 36) / 800 = Rs. 1.62
∴ B.D. = (T.D.) + (B.G.) = Rs. (36 + 1.62)Correct Option: C
B.G. = (T.D.)2 / P.W. = Rs. (36 x 36) / 800 = Rs. 1.62
∴ B.D. = (T.D.) + (B.G.) = Rs. (36 + 1.62)
= Rs. (37.62)

Let T.D. be Re. 1. Then, B.D. = Rs. (11/10) = Rs. 1.10
∴ Sum = Rs. 1.10 x 1/(1.10 - 1)Correct Option: C
Let T.D. be Re. 1. Then, B.D. = Rs. (11/10) = Rs. 1.10
∴ Sum = Rs. 1.10 x 1/(1.10 - 1)
= Rs. 1.10 / 0.10 = Rs.11
So, S.I. on Rs. 11 for 2 years is Rs. 1.10
∴ Rate = (100 x 1.10) / (11 x 2)% = 5%
