Question

A sum of rs 1000 in the form of decrimination of 10 and 50 if total no of notes is 60 .find the no of notes

Answer 1

Answer:

10 and 50

Step-by-step explanation:

Let the number notes of ₹10 be = x

Let the number notes of ₹50 be = y

A/q. sum of the money is 1000

10x + 50y = 1000

10(x+5y)= 10*100

x+5y=100 ----(1)

total number of notes is 60

x + y = 60 ------(2)

NOW, subtract 2 from 1

(x-x) + (5y-y) = (100-60)

4y = 40

y = 10

pit the value of y in 1 or in 2

you will get ,

x = 50

So, the number of notes of ₹10 = 50

and that of ₹50 = 10
