Question

Find compound interest if P=200, R=5 , T=2​

Answer 1

Answer:

CI = P ( 1 + R/100 )^t - P

CI = [200 ( 1 + 5/100 ) ^2 ] - 50

= [200 ( 1 + 1 /20 ) ^2 ] - 50

= [200 ( 21 /20 ) ^2 ] -50

= [200 ( 21 /20 × 21 / 20 ) ^ 2 ]- 50

= [200× 441 /400 ] - 50

= [2 × 441 / 4 ] - 50

= [ 441 /2 ] -50

= 220.5 - 50

= 170.5
