Answer:
2x-y=0 and x+2y=20
are the required Linear equations for the given situation.
Step-by-step explanation:
let the number of ₹50 note be x and ₹100 be y.
so 2x=y
2x-y=0
Then total amount in ₹50 note= ₹50×x=₹50x
and total amount in ₹100 note= ₹100×y=₹100y
According to the question
50x+100y=1000
dividing both side by 50 we get
x+2y=20
