 QUESTION

# A seven digit number starts with _ _ place in the Indian system     (a) Lakhs     (b) Ten thousands     (c) Ten Lakhs     (d) Crores

Hint: Assume any seven digit number and arrange in terms of digits. Then start giving the digit names from right hand side to left hand side as ones, tens, hundreds, thousands, …………, ten lakhs and then see for which digit name is asked and write it.

To find the answer to the given question we will assume a seven digit number, say 1234567.
The above number can be separately arranged in the form of digits as follows,
1000000 + 200000 + 30000 + 4000 + 500 + 60 + 7 = 1234567
As we have written the number in the form of digits and we have to find the Indian System name for seventh digit i.e. 1000000.
As the Indian system starts from ‘Ones’ therefore we will write the number with its digit name in tabular form as show below,

 1000000 2000000 30000 4000 500 60 7 Ten Lakhs Lakhs Ten Thousand Thousand Hundred Tens Ones 1000000 100000 10000 1000 100 10 1

If we observe the above table then we can clearly see that the digit got the name as ‘Ten Lakhs’ by Indian convention. As we have taken any random number therefore we can apply it for any seven digit number.
Therefore a seven digit number starts with Ten Lakhs place in the Indian system.
Therefore the correct answer is option (c).

Note: Do remember all the digit names and always arrange the digits separately to avoid confusion in exam time. For solving this type of problem we should know the right place name of digits in any number.
