10.Which of the following is the set of all the positive integers?
a. {0,1,2,3...} b.(1,2,3,4....} c.{2,4,6,8....} d.{2,5,7,11...}

11.5.The principal rs.A,borrowed at A% per annum simple interest,for A months will amount to:

a.A(1+A^2/12) b.A(1+A^2/1200) c.(A+A^3)/1200 d.A(1+A^2/1200)

• SI=P+(P*R*T)/100
  given that
  P=A rs.
  R=A%
  T=A month so in year it will be A/12 now put the value in formula you will get
  SI=A+(A*A*A)/12*100
  =A+A^3/1200
