Answer:
She has 12 Rs. 50 notes, 4 Rs. 20 notes and 12 Rs. 10 notes.
Step-by-step explanation:
Let the number of —
Rs. 50 notes = 6x
Rs. 20 notes = 2x
Rs. 10 notes = y
Therefore, 6x + 2x + y = 28
=> 8x + y = 28 —— eq(1)
Now, 6x(50) + 2x(20) + y(10) = 800
=> 300x + 40x + 10y = 800
=> 340x + 10y = 800
=> 34x + y = 80 —— eq(2)
Subtracting eq(1) from eq(2) we get —
34x + y - 8x - y = 80 - 28
=> 26x = 52
=> x = 2
Hence, putting the value of x in eq(1) we get —
y = 12
Thus, no. of each note —
Rs. 50 = 6 × 2 = 12
Rs. 20 = 2 × 2 = 4
Rs. 10 = 12
