Let the number of 5 rupee note be x and the number of 10 rupee note be y

Then according to the question,

• 5x+10y=350.............(1)

• Also,x=2y-10............(2)

Putting the value of x from eq .2 in eq. 1 we

get,

$\huge\implies\sf$5(2y-10)+10y=350

$\huge\implies\sf$20y=400

$\huge\implies\sf$y=20

• Putting the value of y in eq.2

we get x=30

Hence, the number oof 5 and 10 rupee note are30 and 20 respectively.
