Estimates vary widely, but it is believed there are up to 100 million children toiling in homes, factories, shops, fields, brothels and on the streets of rural and urban India.
There are at least 150 million Indian children.
The context implies there up to 100 million children involved in child labor in India, but that doesn't say anything about the total number of children in India.  In addition, there may be Indian children that are not in India.  This could also make the total number of Indian children more than 150 million.
