Step-by-step explanation:
Given :-
Meena went to a bank to withdraw Rs.2000.
She asked the cashier to give Rs. 50 and Rs. 100 notes only .
Meena got 25 notes in all .
Solution :-
Let the number of Rs 50 notes and Rs 100 notes be x and y.
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.
