A packet is dropped from a balloon which is going upwards with the velocity $12 \,m/s$, the velocity of the packet after $2$ seconds will be........$m/s$
When packet is released from the balloon, it acquires the velocity of balloon of value $12 \,m/s$. Hence velocity of packet after $2$ sec, will be
$v = u + gt$$ = 12 - 9.8 \times 2 = -7.6 \,m/s$.
