Question

How many Canadian dollars (CAD) can a trader buy with \[400\] Indian rupees?
A. \[4.35{\text{ CAD}}\]
B. \[{\text{7}}{\text{.79 CAD}}\]
C. \[{\text{8}}{\text{.43 CAD}}\]
D. \[{\text{9}}{\text{.56 CAD}}\]
E. \[{\text{7}}{\text{.11 CAD}}\]

Answer 1

Hint: Here we will calculate the answer by using the conversion of the Indian rupee to the Canadian dollar which equals to as below:
\[1{\text{ INR = 0}}{\text{.0177884 CAD}}\]

Complete step-by-step solution:
Step 1: We need to calculate that \[400\] Indian rupees will be equal to how many Canadian dollars.
For that, we will use the conversion of one Indian rupee to CAD as shown below:
\[ \Rightarrow 1{\text{ INR = 0}}{\text{.0177884 CAD}}\]
Step 2: Now, for calculating it for
\[400\]rupees we will substitute this value in the expression \[1{\text{ INR = 0}}{\text{.0177884 CAD}}\] and simply multiplying \[400\] with the CAD value of one Indian rupee as shown below:
\[ \Rightarrow 400{\text{ INR = 0}}{\text{.0177884}} \times {\text{400 CAD}}\]
By multiplying into the RHS side we get:
\[ \Rightarrow 400{\text{ INR = 7}}{\text{.11536 CAD}}\]

Option (E) is the correct option.

Note: In these types of questions, students need to remember the current values of the currency conversion because it may vary from time to time.
Also, there is some important currency conversion which you should remember for calculating these questions as shown below:
\[1{\text{ INR = 0}}{\text{.0177884 CAD}}\] (Canadian Dollar)
\[1{\text{ INR = 0}}{\text{.0134186 USD}}\] (American Dollar)
\[1{\text{ INR = 0}}{\text{.0115364 EURO}}\] (European Dollar)
\[1{\text{ INR = 0}}{\text{.0190459 AUD}}\] (Australian Dollar)
\[1{\text{ INR = 0}}{\text{.0183312 SGD}}\](Singapore Dollar)
Similarly, we should remember the reverse one also, for example, the conversion values from USD to INR or CAD to INR, EURO to INR, etc.
