 is the answer 10

Time of bullet in air = 2u/g = 4 sec

Time to reach highest point = 2 sec

Since bullets are fired every sec, Bullet seven will meet Bullet no 3,4,5 AND 6 That makes 4 bullets(Bullet no. 1 and 2 would have come down by the time 7th is fired)

Now when bullet 7 is coming down it will again meet bullet 8,9,10 and 11

Hence 8 bullets in total

Hope u got that

Plz approve if it helped you
