Meena went to a bank to withdraw \( \$ 1460 \). She asked the cashier to give her \( \$ 10 \) and \( \$ 100 \) notes only. Meena got 29 notes in all. Find how many notes of \( \$ 10 \) and \( \$ 100 \) she received.

Step-by-step Solution
Let's denote the number of $10 notes as \( x \) and the number of $100 notes as \( y \).
Since Meena received a total of 29 notes, we can write the equation:
\[ x + y = 29 \]
The total amount Meena withdrew is $1460, so the total value of the $10 notes and $100 notes is:
\[ 10x + 100y = 1460 \]
We have a system of two equations:
\[ x + y = 29 \]
\[ 10x + 100y = 1460 \]
We can solve this system of equations to find the values of \( x \) and \( y \).
Solve the system of equations by following steps:
- step0: Solve using the substitution method:
\(\left\{ \begin{array}{l}x+y=29\\10x+100y=1460\end{array}\right.\)
- step1: Solve the equation:
\(\left\{ \begin{array}{l}x=29-y\\10x+100y=1460\end{array}\right.\)
- step2: Substitute the value of \(x:\)
\(10\left(29-y\right)+100y=1460\)
- step3: Simplify:
\(290+90y=1460\)
- step4: Move the constant to the right side:
\(90y=1460-290\)
- step5: Subtract the numbers:
\(90y=1170\)
- step6: Divide both sides:
\(\frac{90y}{90}=\frac{1170}{90}\)
- step7: Divide the numbers:
\(y=13\)
- step8: Substitute the value of \(y:\)
\(x=29-13\)
- step9: Simplify:
\(x=16\)
- step10: Calculate:
\(\left\{ \begin{array}{l}x=16\\y=13\end{array}\right.\)
- step11: Check the solution:
\(\left\{ \begin{array}{l}x=16\\y=13\end{array}\right.\)
- step12: Rewrite:
\(\left(x,y\right) = \left(16,13\right)\)
The solution to the system of equations is \( x = 16 \) and \( y = 13 \).
Therefore, Meena received 16 notes of $10 and 13 notes of $100.
Quick Answer
Meena received 16 notes of $10 and 13 notes of $100.
