Income of Avin is 5/8 of the income of Bina. Avin's expenses are one-half of those of Bina, and Avin saves 40% of his income.What percentage of her income does Bina save?

• 25%
  
  Let Bina's income=x & expenditure=y, then Avin's income=5x/8 & expenditure=y/2
  So, Avin's savings=5x/8 - y/2=(40/100)*5x/8
  On simplifying, we get, y=3x/4
  Therefore Bina's savings=x - y = x - 3x/4 = x/4
  In percentage (x/4)*100/x=25%
