Step-by-step explanation:

Answer 2

10 Rs. 50 notes and 15 Rs. 100 notes.

Step-by-step explanation:

Given: Meena went to a bank to withdraw Rs 2000. She asked the cashier to give her Rs 50 and Rs 100 notes only. Meena got 25 notes in all.

Let the number of Rs.50 notes be x, then number of Rs.100 notes will be 25-x.

In total Meena withdrew 2000, so:

50x + 100 (25-x) = 2000

50x + 2500 - 100x = 2000

-50x + 500 = 0

50x = 500

x = 500/50 = 10

So 10 notes of Rs. 50 = Rs. 500

The rest of the notes are Rs. 100. That will be 25 - 10 = 15 notes. Rs. 100 * 15 = Rs. 1500.

So total Rs. 2000 as 10 Rs. 50 notes and 15 Rs. 100 notes.
