250 and 100 notes only. Meena got 25 notes in all. Find how many notes of
50 and Rs 100 she received.​

Answer 1

Answer:

The number of 50 rupee notes (x) is 10

The number of 100 rupee notes (y) is 15

Step-by-step explanation:

let the number of 50 rupee notes = x

and the number of 100 rupee notes = y

therefore according to the question

x + y = 25 ______(1)

we have also given that the h total amount is 2000 therefore

50x +100y = 2000

x + 2y = 40. ______(2)

Now, subtracting =n(1) from (2) , we get

x + 2y - 40 = 0

x + y - 25 = 0

- - +

_________________

y - 15 = 0

y = 15

and from =n(1) we have

x = 25 - 15 = 10

hence, x = 10 and y = 15
