1)My uncle is 100% blind, so how much deductions he is entitled to get under section 80U

2) He has a certificate from govt medical authority, which he drew in 1999 and is in marathi, is it fine?

3) When we send his ITR along with xerox copy of his medical certificate indicating his dissability, does it need to be attested??
