The amount of principal Rs.4000 at compound interest at the ratio of 10% p.a. for 3 years is

a) Rs.4325
b) Rs.5324
c) Rs.3425
d) Rs.5342

• p== 4000
  r== 10
  y== 3
  so,, 1st intrest 4000+400==4400
  2nd 4400+440== 4840
  3rd year 4840+484==5324 ans

• given r=10%
  y=3 years & p=4000
  put these values in formula
  a=p(1+r/100)^y
  ans=5324 rs.

• CI for 2 years a% + b% + a*b/100
  (10 10 10)
  First we'll do for 10 10
  10+10+10*10/100 = 21
  
  now do for 21 & 10 ==> 21+10+21*10/100 ==> 33.1
  
  Total R for 3 years 33.1. Now 33.1 % of 4000 ==> 1324.
  So final answer 4000+1324
