Question

A man spent 3/8 of his salary on rent and 1/3 of the remainder on clothes and feeding, what fraction of his salary is left? If the salary was #144,000

Answer 1

Rent equals to 54,000, remaining 90,000. Clothes and feeding equals to 30,000 remaining 60,000.
60,000/1,44,000*100 = 2/5th of his salary.

Answer 2

Total Salary of man = Rs 144,000
Salary spent on rent by him = 3/8 x 144000
                                               = 54,000
Current amount left = 144000 - 54000 = 90,000
Salary spent on clothes and feeding = 1/3 x 90,000
                                                              = 30,000 
Total amount spent by him = 54,000 + 30,000
                                              = 84,000
Current amount left = 144000 - 84000
                                  = 60, 000
Fraction of salary left = Amount of money left after expenditure
                                       _______________________________
                                       Total salary 
                                    = 60,000/144000
                                    = 5/12
