Number 7? @0:52 Bottom right big block has only has only 2 small blocks available for number 7 in 9th row. So if 7 comes in 9th row and 7 is already present in 7th row then only option available for 7 is 8th row. Since 7 is already present in 4th column so 7 can't come in that entire column. Hence only place for 7 is 8th row 5th column. I hope u understood.
