Answer:
Hi there the answer is 26 notes of ₹10 and 24 notes of ₹20..
Step-by-step explanation:
So first of all we can write let x be the number of ₹10 notes
So now we'll be left with 50-x notes of ₹20.
So we can now write the amount of rupees and the no of notes as
₹10x+ ₹20(50-x)=₹740
=>10x+1000-20x= 740
=>-10x=740-1000 {by doing transposition}
=>-10x= -260
=>x= 260/10
=>x=26
And now we can replace the earlier values of equations with x to get
26 notes of ₹10 and 50-x or 24 notes of ₹20 ...
