Question

Manju had these coins as shown below. She exchanged them all for ₹20 notes. How many ₹20 notes did she get?

$\begin{array}{cc}\text{Denomination}& \text{Quantity}\\ ₹10& 3\\ ₹5& 14\\ ₹2& 8\\ ₹1& 4\end{array}$

• A. 8
• B. 6
• C. 10
• D. 12

Answer 1

The correct option is B

6

$\begin{array}{ccc}\text{Denomination}& \text{Quantity}& \text{Value}\\ ₹10& 3& ₹10\times 3=₹30\\ ₹5& 14& ₹5\times 14=₹70\\ ₹2& 8& ₹2\times 8=₹16\\ ₹1& 4& ₹1\times 4=₹4\end{array}$

For ₹120, she needs 6 notes of ₹20 as
$6\times ₹20=₹120.$

Therefore, she will get 6 twenty rupee notes.
