Question

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. Find how many notes of Rs. 50 and Rs. 100 she received ?

Answer 1

Let the numbers of Rs. 50 notes be x and that of Rs. 100 notes be y. Then,

$x+y=25$ .....(1)

And, $50x+100y=2000⟹x+2y=40$ ......(2)

Solving 1 and 2, we get,

$x=10$ and $y=15$

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