Answer 1

I used hit and trial method.
I assumed that the 80 Rs in 10080 is 1Rs notes and see that if all the conditions given in the question are satisfied.
1Rs note * 80 = 80Rs.
1Rs notes are twice the 100Rs note or we can say no. Of 100Rs note is half of 1Rs note.
Therefore no. Of 100Rs notes = 80/2=40 notes.
100Rs note *40= 4000Rs.
50Rs notes are half the 100Rs note=40/2=20 notes
50Rs note *20=1000Rs.
500Rs notes are one fourth of the 100Rs note = 40/4= 10 notes.
500Rs * 10 notes= 5000 Rs.

Adding all the amount we get 10080 Rs.

So the answer to the question is " No. of 100Rs notes = 40.
