1+ 300 zeros
300 million = 300,000,000 = 8 zeros
A crore (10 million) will have 7 zeros. Therefore: 7 + 2 = 9 zeros in 300 crore.
Thirty of them.
300 000 especially in money.
300 000 000 000=300 billion=11 zeroes.
49 zeros [leading zeros are not used like 001, 002, etc.] This does not include the two zeros in 300 (since the question stated between). So if 300 is included, then 51 zero digits.
300,000 has 5 zeroes.
60, because 20/100 x 300 you can cancel out the zeros in the 100 and the zeros on the 300. then you would get 20 x 3.
