Answer 1

Hope this helps u ❤️

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

Answer 2

$\huge\bigstar\textsf\red{Answer:}$

$\textsf{Let number of 50 rupee notes be x and}$

$\textsf{number of 100 rupee notes be y.}$

$\textsf{According to the first condition}$

$\textsf{50x+100y=2000}$

$\therefore{\textsf{x+2y=40...(1)}}$

$\textsf{According to the second condition.}$

$\textsf{x+y=25...(2)}$

$\textsf{Subtract equation(2) from equation(1), we get}$

$\textsf{x+2y=40}$

$\textsf{-}$

$\textsf{x+y=25}$

________________

$\boxed{\textsf{y=15}}$

$\textsf{Substitute y=15 in equation(2), we get}$

$\textsf{x+15=25}$

$\textsf{x=25-15}$

$\boxed{\sf{\therefore{x=10}}}$

$\textsf{Meena received 10 notes of Rs 50 and 25}$

$\textsf{notes of Rs 100.}$
