months at the rate 6% per annum-
(A) 400
(B) 540
(C) 400
(D) 600​

Answer 1

Answer:

Answer - B

Explanation

Let the sum be Rs. z. Then,

S.I. = Rs. (504 - z)

therefore (z x 5 x 4⁄100) = 504 - z

20z = 50400 - 100z

120z = 50400

z = 420

Now P = 420, R = 10%, T = 5⁄2

S.I. = (420 x 10 x 5⁄100 x 2) = 105

Amount = Rs (420 + 105) = 525
