(A) 1, 81, 81, 818
(B) 18, 19, 818
(C) 18, 17, 818
(D) None of these

Answer 1

Hint: The given number in words is eighteen lakh nineteen thousand eight hundred eighteen. We have four parts which are eighteen lakh, nineteen thousand, eight hundred and eighteen. The numerical value of eighteen lakh is 18, 00, 000, nineteen thousand is 19, 000, eight hundred is 800, and eighteen is 18. Now, add all those and calculate the numerical value of eighteen lakh nineteen thousand eight hundred eighteen.

Complete step by step answer:
According to the question, we are given a number in words and we have to find its numerical value.
The given number in words is eighteen lakh nineteen thousand eight hundred eighteen ………………………………………………(1)
In the above equation, we have four parts which are eighteen lakh, nineteen thousand, eight hundred, and eighteen.
So, first of all, let us write eighteen lakhs into its numerical form.
On writing eighteen lakhs into its numerical form, we get
Eighteen lakhs = 18, 00, 000 ………………………………(2)
Similarly, on writing nineteen thousand into its numerical form, we get
Nineteen thousand = 19, 000 ……………………………………(3)
Similarly, on writing eight hundred into its numerical form, we get
Eight hundred = 800 …………………………………….(4)
At last, on writing eighteen into its numerical form, we get
Eighteen = 18 ……………………………………………(5)
Now, on combining equation (2), equation (3), equation (4), and equation (5), we get
Eighteen lakh nineteen thousand eight hundred eighteen = 18, 00, 000 + 19, 000 + 818 = 18, 19, 818 ……………………………………..(6)
Therefore, the numerical value of Eighteen lakh nineteen thousand eight hundred eighteen is \[18,19,818\].
Hence, the correct option is (B).

Note:
 For this of questions where we are given a number in words. Always approach this type of question by calculating the numerical value part by part. At last, add all those and get the numerical value of the given number in word. There is another approach for this question, i.e by eliminating the options. Option A has 8 digits, so it’s not possible for the given number which is in the range of eighteen lakhs. Then, we have options B and C which differ by one digit, either 9 or 7. The given number has “nineteen” in it, so we can conclude option B as the correct answer.
