Answer 1

Hint: One million is equal to 10 lakhs so 10 million is equal to 100 lakhs, 1 crore is equal to 100 lakhs and 1 crore is equal to 10 millions so using these conversions check the options given in the question.

Complete step by step answer:
Some conversions from lakhs to millions, lakhs to crores and millions to crore is shown below:
1 million is equal to 10 lakhs.
1 crore is equal to 100 lakhs.
1 crore is equal to 10 millions.
Now, we are going to use the above conversions in solving the question.
We need to find one hundred lakhs in terms of crores or millions as per the options given in question.
One hundred lakhs in terms of millions:
1 million = 10 lakhs
So, 100 lakhs = 10 millions…….. Eq. (1)
One hundred lakhs in terms of crores:
1 crore = 100 lakhs
So, 100 lakhs = 1 crore…………. Eq. (2)
Now, checking the options given in the question:
10 million
This is the correct option as from eq. (1) 100 lakhs is equal to 10 millions.
1 million
This is an incorrect option because from eq. (1), 100 lakhs is not equal to 1 million.
100 millions
This is an incorrect option because from eq. (1), 100 lakhs is not equal to 1 million.
10 crores
This is an incorrect option because from eq. (2), 100 lakhs is not equal to 10 crores.
Hence, the correct option is (a).

Note: The most common mistake that tends to happen is writing the number of zeros after lakhs, crores and millions. Another mistake is the conversion from millions to crores so be careful while making these conversions.
