   Answer –B.26 : 27
   Explanation :
   Let Expenditure = Rs.100
   Income(A) = Rs. 130
   Income(C) = Rs. 135
   Ratio = 130 : 135 = 26 : 27

   D.29 : 32
   E.None of these
   
   Answer & Explanation

   Answer –D.29 : 32
   Explanation :
   60 = (I-E)/E  *100
   E(A) = 5/8 x
   45 = (I-E)/E  *100
   E(B) = 20/29 x
   Ratio = 5/8 : 20/29 = 29: 32
