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