Answer 1

Answer:

Interest after 1 year = 81 Rs

Step-by-step explanation:

A = P ( 1 + R/2 * 100 ) ^2n

A = 1600 ( 1 + 5/200 ) ^2*1

A = 1600 ( 1 + 1/40 ) ^2

A = 1600 ( 40 + 1/40 ) ^2

A = 1600 ( 41/40 ) ^2

A = 1600 * 41/40 * 41/40

A = 1681

Interest = Amount - Principal

             = 1681 - 1600

             = 81 Rs
