If the compound interest on a sum of Rs.5000 at the rate of 10% per annum is Rs.1050, then time period is (Interest compounded yearly)

(a) 1YRS
(b) 21/2YRS
(c) 3YRS
(d) 2YRS

• amount=5000+1050=6050
  C.I=P(1+R/100)^n
  6050=5000(1+10/100)^n
  6050/5000=(11/10)^n
  121/100=(11/10)^n
  (11/10)^2=(11/10)^n
  n=2 yrs .

• option D is the answer
  
  after 1st year the interest will be 500/-
  after 2nd year the interest will be 500(1st year)+500(2nd year)+50(10% of 1st year sum)=1050
  so,after 2 years we will get the compound interest as 1050/-

• ans: D
  2yrs
  because total c.I of 5000 at 10% interest for 2 years is 6050
  so 6050-5000 is 1050

• First think for s.i of one year at 10% i.e 500 so for 2 yrs it is 1000
  So in c.i for 2yrs 1050
