Answer 1

Answer:

let the no.of Rs500 notes be x

and no.of Rs 1000 notes be 175-x

ATQ,500x+1000(175-x)=100000

500x=75000

x =75000/500=150

therefore,no.of Rs500 notes =x=Rs150

and no.of Rs1000 notes =175-x=175-150=25

hope it helps....

Answer 2

No. of Rs. 500 notes = 150

No. of RS. 1000 notes = 25

Step-by-step explanation:

Given that,

Total no. of notes = 175

Denominations of these notes = Rs. 500 and Rs. 1000

Amount withdrawn = Rs, 1,00,000

Let the no. of 500 Rs. note be x

And the no. of 1000 Rs. note be 175 - x

A.T.Q.

500x + 1000(175-x) = 1,00,000

⇒ 500x + 1,75,000 - 1000x = 1,00,000

⇒ 500x - 1000x = 1,00,000 - 1,75,000

⇒ - 500x = -75000

⇒ x = 75000/500

∵ x = 150

Thus, No. of Rs. 500 notes = 150

No. of Rs. 1000 notes = 175 -x

= 175 - 150

= 25
