ANSWER

A certain sum of money becomes 625/256 times of itself in 1 year. What is the rate of interest for annum if

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.or, (5/4)^4 = (1+ r/400)^4.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.or, (5/4)^4 = (1+ r/400)^4.or, 5/4 = 1 + r/400.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.or, (5/4)^4 = (1+ r/400)^4.or, 5/4 = 1 + r/400.or, 5/4 - 1 = r/400.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.or, (5/4)^4 = (1+ r/400)^4.or, 5/4 = 1 + r/400.or, 5/4 - 1 = r/400.or, 1/4 = r/400.

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.or, (5/4)^4 = (1+ r/400)^4.or, 5/4 = 1 + r/400.or, 5/4 - 1 = r/400.or, 1/4 = r/400.or, 4.r. = 400

Let P = Rs x. , A =Rs.(625/256).x. , T = 1year = 4 quarter. , rate of interest = r%p.a. = r/4 % p.quarter.A = P .(1 + r/100)^T.or, (625/256).x = x .(1+ r/400)^4.or, (5/4)^4 = (1+ r/400)^4.or, 5/4 = 1 + r/400.or, 5/4 - 1 = r/400.or, 1/4 = r/400.or, 4.r. = 400or, r = 400/4 = 100 % p.a. Answer.
