Answer 2

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.
