Question

Meena went to a bank to withdraw Rs 2000. She asked the cashier to give her Rs 50 and Rs100 notes only. Meena got 25 notes in all. Find how many notes of Rs 50 and Rs100 she received.

Answer 1

Let Meena got x and y notes of Rs. 50 and Rs100 respectively.

Then x + y = 25               ...(i)
50x + 100 y = 2000
⇒ x + 2y = 40                   ...(ii)

Subtracting (i) from (ii), we get
y = 15
From (i), x = 25 – 15 = 10

Thus, Meena had 10 notes of Rs 50 and 15 notes of Rs 100.
