Question

calculate the amount and CI on rs. 4000at 2.5% per annum compounded annualy for 3 years
​

Answer 1

Step-by-step explanation:

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

= 4000 ( 1+ 2.5 /100)^3 = 4000 ( 1025/1000)^3 = 4307.57

c.i = A- P = 4307.57 - 4000 = 307.57

Answer 2

Step-by-step explanation:

$A = P {(1 + \frac{R}{100})}^{N} \\ = 4000 {(1 + \frac{2.5}{100}) }^{3} \\ = 4000 {(1 + 0.025)}^{3} \\ = 4000 {(1.025)}^{3} \\ = 4000 \times 1.07689 \\ = \large{\boxed{ \bold{ \underline{ \underline{4307.56}}}}}$
