Key Facts

In the Indian comma system, we place the first comma after the hundreds place (three digits), and then we place a comma after every TWO digits (1,00,00,000).

In the International comma system, they place a comma after every THREE digits consistently (10,000,000).

1. The Correct Answer

There are exactly 100 Lakhs in One Crore.

  • If you have one hundred bundles of 1 Lakh rupees, you officially have 1 Crore rupees.

2. The Mathematical Proof (Counting the Zeros)

To prove this, we simply look at the massive number of zeros:

  • 1 Lakh is written as 1,00,000 (It has 5 zeros).
  • 1 Crore is written as 1,00,00,000 (It has 7 zeros).
  • If you take 1 Lakh ($10^5$) and multiply it by 100 ($10^2$), you add two extra zeros. This gives you 7 zeros, which perfectly equals 1 Crore ($10^7$).
  • Formula: $1,00,000 \times 100 = 1,00,00,000$.

3. The International System Equivalent

If you are watching a Hollywood movie or reading foreign news, they do not use Lakhs or Crores. They use Millions.

  • 10 Lakhs = 1 Million.
  • Therefore, 1 Crore = 10 Million.
