Question

A bag contains Rs500 in notes of denomination of Rs 10 and Rs 50. If the total number of notes is 30, then the number of Rs 10 notes is​

Answer 1

Answer:

Let us assume the number of 5 rupees note be 'x'. Then the number of 10 rupees note will be '90-x' (Total number of notes=90)

The total amount is 500. So according to the question:

5x+10(90-x)=500

5x+900–10x=500

-5x=500–900

-5x=—400

X=—400/—5 (Since, — and — = +)

X=400/5

X=80

Hence, according to our solution:—

Number of 5 rupees note=X that is 80

And number of 10 rupees note=(90-x) that is (90–80)=10

Therefore, there are 80 five rupees note and 10 ten rupees note..
