a. 3500
b. 70
c. 1500
d. None of these

• total currency notes =85 let no.of 50 rs notes=x
  so (85-x)*100+x*50=5000
  so x=70

• 100x+50y=5000
  x+y=85
  solving both equations , we get,
  y=70,x=15
  so total amount in denomination of rs 50 = 50*70=3500

• let 50 rupee notes=x
  then 100 rupee notes= 85-x
  then
  50x+100(85-x)=5000
  x=70
  so
  70*50=3500
