The sum of rupees 500 is in form of denominator of. Rupees 50 and 10. the total number of notes is 90. Find the cost of notes in each.



Number of notes=90
Let the number of Rs.50 notes be x
Then , number of Rs.10 notes=(90-x)
Value of all the Rs.50 notes=Rs.50*x=Rs.50x
Value of all the Rs.10 notes=Rs.10*(90-x)=Rs.(900-10x)
Total amount=Rs.500
Given, 50x+900-10x=500
Since the number of notes is not a natural number , the question is impossible.
(Important note:You can see that if all the notes are of Rs.10 then, total value of them=10*90=Rs.900 which is <500.SO THE QUESTION IS IMPOSSIBLE)
