Question

Write the following in numerals:
Ten lakh ninety thousand nine hundred nine.
(a) 10,09,099
(b) 10,90,909
(c) 10,909
(d) 10,09,909

Answer 1

Hint: We know that one lakh = 100000, here we have ten lakh. That means we have to multiply one lakh by 10. Similarly one thousand = 1000, we have ninety thousand here. One hundred = 100, we have nine hundred. At last we have nine. Add these results together to get the numeral.

Complete step-by-step answer:
A numeral is a symbol or name that stands for a number.
Like in the above question we have, ten lakh ninety thousand nine hundred nine. This represents a number and it is in word form. We need to write the same amount by using digits.
A digit is a single symbol used to make numerals.
We know that one lakh = 100000. Therefore ten lakh will be one lakh multiplied by 10.
Ten lakh = 1000000.
Then we have ninety thousand. We know that one thousand = 1000, ninety thousand will be one thousand multiplied by 90. Therefore,
Ninety thousand = 90,000.
Then we have nine hundred. That means one hundred multiplied by 9. Therefore,
Nine hundred = 900.
At last we have nine. That means one multiplied by 9. Therefore,
Nine = 9.
Now, we will add all the above results.
1000000+90000+900+9 = 10,90,909
Therefore,
Ten lakh ninety thousand nine hundred nine = 10,90,909.
Hence option (b) is correct.

Note: Alternatively we can find out the answer by cross checking the options. Like in the first option we have ten lakh nine thousand and ninety nine which is not the same as the given question. Therefore, option (a) is not correct.
