The monthly income ratio of A and B is 6:5. The ratio of their monthly expenditures is 3:2. If A saves one-fourth of this income, find the ratio of their monthly savings.
A. 3:5
B. 3:4
C. 1:2
D. 3:8
E. 3:7

• let the monthly income of b be rs.100
  so, 6/5=a/100 a=120 (x multiply)
  savings of b = 100*1/4= rs.25
  exp of b= 100-25=75
  exp ratio:-
  3/2=a/75 a= 112.5 (x multiply)
  savings of a = 120-112.5= 7.5 rs
  savings ratio = a/b
  = 7.5/25 (x by 10 both numerator and denominator)
  = 75/250
  =3/10
  
  remember income= exp + savings

• ans is 3:4
  let income of B=100
  A=120
  saving of A =30
  expenditure of A =90
  expenditure of B=60
  120-90=30
  100-60=40
  ratio=3:4
