Question

Convert \[200\] Million dollars in rupees.

Answer 1

Hint: To Convert \[200\] Million dollars in rupees we have to first find the difference between Indian place value system and international place value system. We will write \[200\] Million in numeric form and then convert this to Indian place value system. As \[1{\text{ USD}} = 74.28{\text{ INR}}\], so we will multiply with \[74.28\] to find the result in Indian rupees.

Complete step by step solution:
Here, we should know the Indian place value system and international place value system.
Indian place value system involves uses of lacks, crores, etc. while international place value system involves uses of millions, billions, etc.
In Indian place value system, we start grouping the numbers from right to left in a group of three and further in a group of two whereas in the international place value system we group the number from right to left in a group of three only.
Therefore, we can write \[{\text{200 Million = 200,000,000}}\] in international place value system and \[{\text{200 Million = 20,00,00,000}}\] i.e., \[{\text{200 Million = 20 Crores}}\] in Indian place value system.
Now, we know the conversion rate that \[1{\text{ USD}} = 74.28{\text{ INR}}\].
Therefore, \[200\] million dollars will be equal to \[{\text{20 Crores}}\] multiplied by \[{\text{INR }}74.28{\text{ }}\] i.e., \[ \Rightarrow 200{\text{ Million dollar= 20,00,00,000}} \times {\text{INR 74}}{\text{.28}}\]
On simplification, we get
\[ \Rightarrow 200{\text{ Million dollar = INR 14,85,6}}0,00,000\].
Therefore, \[200\] Million dollars is equal \[{\text{14,85,6}}0,00,000{\text{ INR}}\].

Note: In these types of questions, the most important thing is conversion from the international place value system to Indian place value system. We should keep in mind that in Indian place value system we start with a group of three and further in a group of two whereas in an international place value system we group the numbers from right in groups of three only.
