Question

after spending 80 percent of his income and giving 10 percent of the remainder in a charity,a man has ₹46260 left with him.fimd his income.

Answer 1

Suppose, if our income is 100%, and we spent 80% so now our income is 20% (100%-80%=20%) and we give 10% of remain 20% so our income is 18% and 18% = 4626 
So 18%=4626 
and 100% = 4626X100/18=25700 
answer is 25700

Answer 2

10% = 46260
80%=10X8
=46260X8
=3,70,080₹

10%+80%=90%

ruppes remaining =100%-90%
=10%
=46260₹
Total ruppes =370080+ 46260
=416340
