Question

plzz help me out in solving this question

Answer 1

meenA has 10 notes of rs 50 and 15 notes of rs 100

Answer 2

Given that the cashier gave Meena 50 and 100 notes only.

Let the number of 50 rupees Meena received = x.

Let the number of 100 rupees Meena received = y.

Given that Meena got 25 notes in all.

x + y = 25  

x = 25 - y  ------ (1)


Given that Meena went to withdraw 2000 rupees.

50x + 100y = 2000

50(25 - y) + 100y = 2000

1250 - 50y + 100y = 2000

1250 + 50y = 2000

50y = 2000 - 1250

50y = 750

y = 750/50

y = 15.


Substitute y = 15 in (1), we get

x = 25 - y

x = 25 - 15

x = 10.


Therefore the number of 50 rupees Meena received = 10.

                  the number of 100 rupees Meena received = 15.



Hope this helps!
