in how many years will a sum of money become 8 times it self at 7 % per annum simple interest(in years)?

• 100 years
  
  If x is principal and 8x is final amount with interest, then
  interest = 7x =x*7*t/100
  so t=100 yrs

  Assume P= 100, then SI = 700, R = 7 %, T=?
  T= SI X 100 / P X R
  = 700 X 100 / 100 X 7 = 100 YRS Ans.
