Before an increment in Ram's salary,the total expenditure of the family was 60% of the total income.ram's salary was equal to the total savings of the family then if ram got 50% increment in his salary then what are the new total savings of the family as a percentage of its new total income if its expenditure is kept constant?pl. provide sol.

1) 33 1/3%
2) 50%
3) 66 2/3%
4) 40%

• let income of family=100
  expenditure= 60
  saving= ram's income=40
  after increasing ram's salary=40*150/100=60
  saving increased=20
  so new savings =60
  total income becomes=100+20=120
  so saving%=60/120*100=50%
  option (2) is correct
