Zakaat

Q: We have a joint family system. I am financially stable but my elder brother is struggling to survive. He is married and his wife shares a kitchen with us.

My question is can i give Zakat to my elder brother? As i said we have a shared kitchen, so I'm afraid if i give Zakat to my elder brother and with that money he brings some food, so that food will be halal for me? Even though it is not my intention that my brother bring food and share with us, but if some day it happens then what should i do?

Q: If I have 20 lakh rupees in my account at the start of the year and after completion of one year this amount is increased to 30 lakh over the last twelve months gradually on monthly savings from my source of income. To my knowledge if an amount is in my possession for one year constantly, the zakat is due on that amount, therefore I assume that I should calculate my zakat on 20 lakh because the increase in my amount is month by month and full one year has not been passed over this amount. Am I correct or I should calculate my zakat on 30 lakh?
