Select all the correct options.

• A. She received 10 notes of Rs 50
• B. She received 14 notes of Rs 50
• C. She received 15 notes of Rs 100
• D. She received 17 notes of Rs 100

Answer 1

Answer: (A), (C)

The correct options are
A

She received 10 notes of Rs 50

C

She received 15 notes of Rs 100

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