• lets take the income of A=3k
  lets take the income of B=4k
  as welllas expenditures are 4x,5x
  savings =income-expenditures
  so savings ratio is =3k-4x/4k-5x;
  now equate the aboue ratio with the given options only one option will satisify
  the equation
  the options are
  A)9:10 B)3:4 c)13;20 D)4:5
  option a 3k-4x/4k-5x=9/10;
  if we solve the abouve we will get x=-6/5k income should not be negative
  so option a is wrong
  solve the remaining similarly then we will get the solution

• income ratio is 3:4
  then we suppose that 30000 and 40000.
  now exp ratio is 4:5
  so we subtract 24000 from 30000 and 30000 from 40000.
  now both have remaining amount is 60000 and 10000
  so savivg ratio 3:5
  ANSWER == 3:5
