Consider the number of Rs 500 notes to be 'x'.
Consider the number of Rs 100 notes to be 'y'.

Since the total amount is given as 50,000
     500x+100y=50000 .
⇒5x + y = 500       ⇒(equation 1)

Since the total number of notes is 200,
  x +y = 200 .
⇒y= 200 - x             ⇒(equation 2)

substituting eqn (2) in eqn (1)
 5x + 200 - x = 500
               4x = 300
                 x = 75.
 substitution the value on x in any eqn, we get y=125.
 Therefore, no of Rs 100 notes ⇒125
                 no of Rs 500 notes ⇒75
1 5 1
