Meena went

Answer :

To find: Notes of denomination Rs 50 and Rs 100.


Let the number of Rs. 50 and Rs. 100 notes be ‘a’ and ‘b’.

Given, Meena went to a bank to withdraw Rs 2000. She asked the cashier to give her Rs 50 and Rs 100 notes only.

50a + 100b = 2000

a + 2b = 40 …… (1)

Also, Meena got 25 notes in all.

a + b = 25 ……(2)

(1) – (2)

a+2b–(a+b) =40–25


b = 15

Put the value of b in eq. 1 to get,



Thus, a = 10

Therefore, Meena received 10 notes of denomination 50 and 15 notes of denomination 100.
