meena went to a bank to withdraw Rs. 2000. she asked the casier to give her Rs. 50 and Rs.100 notes only meena got 25 notes in a

Zanzabum

Answer: 10 Rs.50 notes. ; 15 Rs.100 notes

Explanation:

Let the number of RS 50 notes received be x

Let the number of RS 100 notes received be y

Since Meena got 25 notes in total, this means that:

x + y = 25 ...... equation i

Since Meena went to a bank to withdraw Rs. 2000. This means:

50x + 100y = 2000 ...... equation ii

Combining both equations

x + y = 25 ....... i

50x + 100y = 2000 ...... ii

Multiply equation i by 50

Multiply equation ii by 1

50x + 50y = 1250 ...... iii

50x + 100y = 2000 ...... iv

Subtract equation iii from iv

50y = 750

y = 750/50

y = 15.

Therefore, since x + y = 25

x + 15 = 25

x = 25 - 15

x = 10

The number of Rs.50 notes received is 10

The number of Rs.100 notes received is 15.
