Equations to Find Number of Rs.200 and Rs.100 Notes
To find the number of Rs.200 notes as x and the number of Rs.100 notes as y, we can set up the following pair of equations:
1. 200x + 100y = 2000 (Total value of notes given)
2. x + y = 11 (Total number of notes returned)

Finding the Number of Rs.200 Notes
To solve these equations, we can use the method of substitution or elimination. Let's use substitution in this case:
From equation 2, we have x = 11 - y.
Substitute this value of x into equation 1:
200(11 - y) + 100y = 2000
2200 - 200y + 100y = 2000
100y = 200
y = 2
Now that we have found the number of Rs.100 notes (y = 2), we can find the number of Rs.200 notes:
x = 11 - y
x = 11 - 2
x = 9
Therefore, Shipra received 9 notes of Rs.200 each.
