Dear aspirant !

Hope you are doing well ! No ,not at all it is very hard for any Indian to earn such a large amount in india , According to a research Australia neurosurgeon earn maximum in the whole world and that is approx 3 crore which is very very less than the amount you are asking about . Only to reach 3 crore you need high practice and experience in your field so it seem very funny to only think about 75 crore in India ,firstly try to reach only 1 crore by your hardwork.
