Let the original money be ₹ 100.
Money spent on machinery =₹35
Money spent on raw material =₹40
Money spent on staff =₹10
Money left =100−85=₹15
If money left is ₹15, the original money =100
So, if money left is 60,000 , the original money
=

100

15

×60,000=₹400000
Money spent on machinery and raw material
=400000×75%=₹300000
