Help!!!

Ananya went to a bank to withdraw ₹2000 .she asked the cashier to give her in ₹50 and ₹100 notes only .She got 25 notes in all.Can you tell how many notes each of ₹50 and ₹100 she received ?

Answer 1

$\mathfrak{Answer}$

Step-by-step explanation:

Let the number of ₹50 notes Be “x”

Let the number of ₹100 notes be “y”

Then, x+y = 25—(1)

And 50x + 100y = 2000 —(2)

By substitution method ,

From Equation (1) , x = 25-y

Substitute it in Equation (2)

50(25-y) + 100y = 2000

1250-50y +100y = 2000

50y = 2000-1250

50y = 750

y = 750/50

y = 15

Now ,

x = 25-15

x = 10

Hence Ananya received $\boxed{10}$ ₹50 notes And $\boxed{15}$ ₹100 notes .

Answer 2

Let The number of notes ₹50 be x

and number of notes of ₹100 will be y

Therefore:

Equation Will be like this

x+y=25

x=25-y.............[1]

Therefore

The total amount only in ₹50 notes =50x

while in ₹100 notes=100y

We know that Total Amount is 2000

Second Equation Formed will be

50x+100y=2000

now from [1]

50(25-y)+100y=2000

1250-50y+100y=2000

50y=750

y=15

Now in Eq [1]

x=25-(15)

x=10

Therefore

She recieved 10 notes of rs50 and 15 notes of rs 100
