- 25%
Let Bina's income=x, then Avin's income=(5/8)x
As Avin saves 40% of his income, so Avin's expenses are 60% of income=(60/100)*(5/8)x=(3/8)x
Thus Bina's expenses=2*Avin's expenses=2*(3/8)x=(3/4)x
Therefore Bina's savings=x - (3/4)x = (1/4)x
Hence Bina's saving in % = [(1/4)x/x]*100=25% - 6 years agoHelpfull: Yes(0) No(0)
