Answer 1

Hint: In this question, we first need to note the Indian system and international system .Then find the face value and place value of the all respective digits in the given 7 digit number accordingly and then write the number so obtained then write it in words in the international system by converting accordingly from the Indian system.

Complete step-by-step answer:
Let us first represent the international system and Indian system
Indian system

Ones	1
Tens	10
Hundreds	100
Thousands	1,000
Ten thousands	10,000
Lakhs	1,00,000
Ten lakhs	10,00,000

International system

Ones	1
Tens	10
Hundreds	100
Thousands	1,000
Ten thousands	10,000
Hundred thousands	100,000
Million	1,000,000

Now, the given conditions in the question are in terms of Indian system
Now, ones period include ones, tens and hundreds, thousands period include thousands and ten thousands and lakhs period include lakhs and ten lakhs
Let given in the question that 1 in ones period, 3 in thousands period and 2 in the lakhs period
Now, the seven digit number can be written as

2

2

3

3

1

Now, in the international system this can be written as
Two million, two hundred thirty three thousand, one hundred eleven
So, the correct answer is “Option A”.

Note: Instead of writing it in terms of the international system if we write in the Indian system which will also be given in the options then the whole answer will be incorrect as the system plays an important role in choosing the optionIt is also to be noted that the hundreds place comes under one's period because if we consider it under thousands, then 1 replaces with 3 which results in an incorrenumber and so the final answer.
