D) None

Answer 1

Hint: First check the number of digits and identify the periods of both of the given numbers. Check all the places and then based up on it, compare both the numbers to find out which number is greater, smaller, or are they equal.

Complete step-by-step answer:
Firstly, assign the periods to both of the given numbers.
The first number is 67389145.
After putting commas, it should be written as: 6,73,89,145.
In words it can be written as six crore seventy three lakhs eighty nine thousand one hundred forty five.
The second number is 673891450.
After putting commas, it should be written as: 67,38,91,450.
In words it can be written as sixty seven crore thirty eight lakhs ninety one thousand four hundred fifty.
From this distinction, it is clear after comparing that the second number is greater than the first number.
So, it is clear that 67389145 < 673891450.

Therefore option A is the correct answer.

Note: Alternate approach to the solution:
Always count the number of digits in both the numbers before checking according to the number system.
If both numbers have equal digits, then go for the number system to know whether both the numbers are equal or not.
If the number of digits are not equal, then it is obvious that the number with more number of digits is greater.
The comparison of two numbers is the easiest way to find out the greater and smaller number.
