Answer 2

Answer:

Let the number of Rs 50 notes and Rs 100 notes be x and y respectively.

According to the question,

x + y = 25 ...

(i) 50x + 100y = 2000 ...

(ii) Multiplying equation

(i) by 50, we get 50x + 50y = 1250 ...

(iii) Subtracting equation (iii) from equation (ii), we get

50y = 750

y = 15

Putting this value in equation (i), we have x = 10

Hence, Meena has 10 notes of Rs 50 and 15 notes of Rs 100.
