Answer 1

Hint: To write a number given in the words into numeral form we will use the rule of Indian number system. In Indian number system a number has two values-place value and face value. We use the place value rule of ones, tens, hundreds, thousands and so on to solve this question.

Complete answer:
We have to write Thirty-one crore fifty-five lakh thirty-two thousand eight hundred in numerals.
Now, starting from the right hand side we have given eight hundred, so the last digits of the numeral will be 800, i.e. 0 at one place, 0 at tens place and 8 at hundreds place.
Now, we have given thirty-two thousand, so we can write the number as 32,800.
Now, we have fifty-five lakh, so we can write the number as 55,32,800.
Now, we have given Thirty-one crore so the number will be 31,55,32,800.
The place value of a digit is always counted from the right hand side.

So, Thirty-one crore fifty-five lakh thirty-two thousand eight hundred in numerals is written as $31,55,32,800$.

Option A is the correct answer.

Note:
The key point to solve such types of questions is to always try to write the numeral from the right hand side. Always count the face value of the given number. Place value gives the position of a digit in the number while face value gives the value of the digit.
