Answer 2

Answer:

let the no. of 50rs notes be x and the no. of 100rs notes be y

Atq,

x+y =25---(1)

50x+100y=2000--(2)

multiply equation (1)by 100

we get, 100x+100y =2500---(3)

equation (3)-equation (2)

100x+100y=2500

-50x-100y= -2000

-------------------------

50x=500

x=500/50

x=10

Putting the value of x in equation (1)

10+y=25

y=25-10

y=15

Hence, the no. of 50rs note is10 and 100rs note is 15
