Question

Write the Linear equation for the given situation: If the amount in your father’s wallet is ₹ 1000. The number of notes of ₹ 100 are two times the notes of ₹ 50, then find the count of each type of notes in the wallet

Answer 1

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
