Given : Arun went to a shoe store and purchased a pair of shoes worth ₹500. He gave a ₹2000 note to the owner of store and he was returned 11 notes in denominations of ₹200 and ₹100.
number of ₹200 notes is x and that of ₹100 is y,
To Find : linear equation will be formed for this information.
Solution:
purchased a pair of shoes worth ₹500.
He gave a ₹2000 note
Return = 2000 - 500 = 1500 Rs
number of ₹200 notes is x
Hence Value is 200x
number of ₹100 is y
Hence value is 100y
Total Value returned = 200x + 100y
200x + 100y = 1500
Dividing both sides by 100
=> 2x + y = 15
2x + y = 15
