Hint:- In Indian system \[abcdefgh\]will be written as \[a,bc,de,fgh\]. And in the International system, it will be written as \[ab,cde,fgh\].
We have to write all numbers in Indian and International System of Numeration.
So, as we know that,
In Indian system of numeration starting from left to right.
First, we place comma after three digits and then place comma after every 2 digits.
till we reach at the rightmost digit of a number.
But in the International system of numeration starting from left to right.
We place a comma after every three digits, till we reach the rightmost digit of the number.
So, if \[abcdefgh\] be any number then, this number in Indian system can be written as,
\[ \Rightarrow \]In Indian system of numeration number will be represented as \[a,bc,de,fgh\]
\[ \Rightarrow \]And, in International system of numeration number will be represented as \[ab,cde,fgh\]
 So, now solving all four numbers,
\[(i)\]
Indian system \[ \Rightarrow {\text{5,27,864}}\]
International system \[ \Rightarrow {\text{527,864}}\]
\[(ii)\]
Indian system \[ \Rightarrow {\text{95,432}}\]
International system \[ \Rightarrow {\text{95,432}}\]
\[(iii)\]
Indian system \[ \Rightarrow {\text{1,89,50,049}}\]
International system \[ \Rightarrow {\text{18,950,049}}\]
\[(iv)\]
Indian system \[ \Rightarrow {\text{7,00,02,509}}\]
International system \[ \Rightarrow {\text{70,002,509}}\]

Note:- Whenever we are asked to write any number in Indian system of numeration,
then, we first place comma after three digits starting from right and then place comma after
every 2 digits till we reach at the rightmost digit of a number. And in International system
starting from left to right, first we place comma after every three digits, till we reach the
rightmost digit of the number.
