Question
The monthly income of a man is Rs. 16, 000. 15 percent of it is paid as income-tax and 75% of the remainder is spent on rent, food, clothing, etc. How much money is still left with the man?
Solution
Monthly income = Rs. 16,000
Income tax
= Rs. `(16,000 xx 15)/(100)`
= Rs.2,400
Remaining
= (16,000 - 2,400)
= Rs. 13,600
Amount spent to rent, food clothing etc.
= `(13,600 xx 75)/(100)`
= `(13,600 xx 3)/(4)`
= 3,400 x 3
= Rs. 10,200
Balance left
= 13600 - 10200
= Rs. 3400
