Advance tax on profit of shares held for more than 12 months

Hi, consider a person 'X'. He bought shares worth Rs. 3,60,000 in April, 2015. He sold shares worth Rs. 48000 in August, 2016 and got profit of Rs.9600. Is this person liable to pay any advance tax? He will probably sell rest of the shares too soon and his profit may reach to Rs. 1,20,000. Will then he be liable for advance tax? Thanks. This person has no other source of income as he is unemployed as of now.
