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,

000001 billion = 100 crores= 100 * 1 crore = 10 * 7 zeroes = 10,

00000001 trillion = 1lakh crores= 1lakh * 1 crore = 5 zeroes * 7 zeroes = 1

000000000000

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

000000000000$To convert above into Indian rupees, multiplying by the exchange rate: i.e. 79.63 ( 1 US $= 79.63 Indian rupees)

= (5*79.63) *

000000000000Indian rupees = 398.15000000000000Indian rupees
