The incomes of A and B are in the ratio 4:5 and their expenditures are in the ratio of 5:6. If A saves 1/4th of his income find the ratio of their savings.
A. 5 : 7
B. 4 : 5
C. 6 : 11
D. 3 : 5
E. 5 : 9

• Income:
  A= 4x
  B= 5x
  expenditure:
  A=5y
  B=6y
  saving:
  A = 4x-5y = x => 3x=5y
  B = 5x-6y = 5x- 18x/5 = 7x/5
  required ratio = x/(7x/5) = 5/7
  
  Hope this helps..!!
