Question

How much \[1\] Million US dollars is equal to how many crores? Rate: \[\$ 1\] is equal to \[{{INR }}65\].

Answer 1

Hint: To find that \[1\] Million US dollars is equal to how many crores we have to first find the difference between Indian place value system and international place value system. We will write \[1\] Million in numeric form and then convert this to Indian place value system. Then we will multiply with \[65\] to find the result in crores.

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 \[1{{ Million\; = 1,000,000}}\] in international place value system and \[1{{ Million\; = 10,00,000}}\] i.e., \[1{{ Million\; = 10 Lakhs}}\] in Indian place value system.
Now, given in the question that \[\$ 1\] is equal to \[{{INR }}65\].
Therefore, one million US dollars will be equal to \[{{10 Lakhs}}\] multiplied by \[{{INR }}65\] i.e., \[ \Rightarrow 1{{ Million US dollar\; = 10,00,000}} \times {{INR }}65\]
On simplification, we get
\[ \Rightarrow 1{{ Million US dollar\; = INR }}6,50,00,000\] which is equal to \[6.5{{ Crores}}\] in INR.
Therefore, \[1\] Million US dollars is equal \[6.5{{ crores}}\]
So, the correct answer is “\[6.5{{ crores}}\]”.

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.
