If 1 is added to the greatest 7-digit number, it equals
10 thousand
1 lakh
10 lakh
1 crore
Step-by-step explanation for a beginner
1. First, understand what a 7-digit number is: it has 7 digits (for example 1,000,000 is the smallest 7-digit number).
2. The greatest (largest) 7-digit number is:
\(9,999,999\)
3. Now add 1 to that number:
\(9,999,999 + 1 = 10,000,000\)
4. Read the result in the Indian number system. The number \(10,000,000\) is called 1 crore:
\(10,000,000 = 1\) crore.
5. So the correct option is (D) 1 crore.
