Hint: We use the concepts of both the Indian and International number systems to write the names of the given two numbers.
* Indian number system: In this system we count from the right hand side of the number and proceed to left hand side with order ones, tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, crore and so on.
* International number system: In this system we count from the right hand side of the number and proceed to the left hand side with order ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, hundred millions and so on.

Complete step-by-step solution:
We write number names for each number separately.
 1) 236749:
Indian number system:
Ones place has digit 9
Tens place has digit 4
Hundreds place has digit 7
Thousands place has digit 6
Ten thousands place has digit 3
Lakhs place has digit 2
Separate the number using commas i.e. 2,36,749
$$\Rightarrow$$Number name of 236749 is: Two lakh thirty six thousand seven hundred and forty nine.
International number system:
Ones place has digit 9
Tens place has digit 4
Hundreds place has digit 7
Thousands place has digit 6
Ten thousands place has digit 3
Hundred thousand place has digit 2
Separate the number using commas i.e. 236,749
$$\Rightarrow$$Number name of 236749 is: Two hundred thirty six thousand seven hundred and forty nine.
2) 48670002:
Indian number system:
Ones place has digit 2
Tens place has digit 0
Hundreds place has digit 0
Thousands place has digit 0
Ten thousands place has digit 7
Lakhs place has digit 6
Ten lakhs place has digit 8
Crores place has digit 4
Separate the number using commas i.e. 4,86,70,002
$$\Rightarrow$$Number name of 48670002 is: Four crore eighty six lakh seventy thousand and two.
International number system:
Ones place has digit 2
Tens place has digit 0
Hundreds place has digit 0
Thousands place has digit 0
Ten thousands place has digit 7
Hundred thousand place has digit 6
Millions place has digit 8
Ten millions place has digit 4
Separate the number using commas i.e. 48,670,002
$$\Rightarrow$$Number name of 48670002 is: Forty eight million six hundred seventy thousand and two
Now we write the number names in appropriate places in the table.
$$\therefore$$Number names according to each system are:

Number	Indian System	International System
236749	Two lakh thirty six thousand seven hundred and forty nine	Two hundred thirty six thousand seven hundred and forty nine
48670002	Four crore eighty six lakh seventy thousand and two	Forty eight million six hundred seventy thousand and two

Note: Students many times make mistakes while writing the number names using the international system as they are familiar with Indian number system and use the same comma technique in the international number system. Keep in mind we separate the number using commas in the international number system with each interval containing exactly 3 digits.
