# Trick to write the number of zeros in 1 million, billion, or trillion

Remember always:

You can remember above as 7crore 5lakhs ( i.e. there are 7 zeroes in 1 crore and 5 zeroes in 1 lakh).

One more thing to remember-

Trick: 1 billion can be obtained by multiplying 1000 to 1 million

Similarly, 1 trillion can be obtained by multiplying 1000 to 1 billion

Practice time:

1 million = 10 lakhs= 10 * 1 lakh = 10 * 5 zeroes = 10,00000

1 billion = 100 crores= 100 * 1 crore = 10 * 7 zeroes = 10,0000000

1 trillion = 1lakh crores= 1lakh * 1 crore = 5 zeroes * 7 zeroes = 1 00000 0000000

So, we can see that 1 trillion has 12 zeroes.

In 2019, Government of India envisioned of making India a $5 trillion economy. So how to write 5 trillion dollars? Lets first write 5 trillions in lakhs and crore form. 5 lakhs crores US dollars= 5 * (5 zeroes) * (7 zeores) = 5 00000 0000000$

To convert above into Indian rupees, multiplying by the exchange rate: i.e. 79.63 ( 1 US $= 79.63 Indian rupees) = (5*79.63) * 00000 0000000 Indian rupees = 398.15 00000 0000000 Indian rupees ## What is a Unicorn?

A person who has a consistent annual income of 1 billion US dollars i.e. 100 crores$

i.e., 100 crores dollars or if a person has a consistent income of (100*75) crores Indian rupees = 7500 0000000 Indian rupees or 7500 crores then, we can say he is a billionaire.
