Answer 2

Answer:

Rate percent = 22.916 %

Step-by-step explanation:

P = Rs 3136

C.I = Rs 345

A = Rs 3481

T = 2 years

A = P ( 1 + r/100) ^t

A = P ( 1 + r/100) ^2

= 3136 ( 1 + r/100) ^ 2

√3481 / 3136 = ( 100 + r / 100)

59/ 56 * 100 = 100 + r

59 * 50/24 - 100 = r

59 * 25/12  - 100 = r

1475/12 - 100 = r

r =  122.916 - 100 = 22.916

Rate percent = 22.916 %
