Answer 1

Ratio = 5:4
Let Number of 100 rupee notes be 5x
Let Number of 50 rupee notes be 4x
ATQ
5x+4x = 7000
9x = 7000
x = 777 (approx)

Therefore 100 rupee notes = 5×777 = 3855
50 rupee notes = 4×777 = 3108

Answer 2

number of 100 rupee = 5x

number of 50 rupee = 4x

Total rupee = 7000

(5x X 100) + (4x X 50) = 7000

500x + 200x = 7000

700x = 7000

x = 10

number of 100 rupee = 5x = 50

number of 50 rupee = 4x = 40
