Question

A sum of Rs 500 is in the form of denominations of Rs. 5 and Rs. 10. If the total number of notes is 90 find the number of notes of each type​

Answer 1

Answer:

Step-by-step explanation:

Lets assume you have x notes of rs 5 and y notes of rs 10. So you have

x+y =90

And 5x+10y=500.

Putting x=10-y in 2nd equation you have

5(90-y)+10y=500.

450–5y+10y=500

5y=500–450

y=50/5=10.

Hence x=90–10=80.

So answer is 80 notes of rs 5 and 10 notes of 10.
