Answer:

A.

Step-by-step explanation:

Let the number of the birds apart from the newcomer, be x.

x/2 + 1 = 100

which means,

x/2 = 100 - 1,

this gives us a 99.

x/2 = 99.

To get the actual number and kill the fraction we multiply by 2.

x = 2 x 99

...

x= 198...

Therefore,

The total birds flying were 198.

PROOF:

198/2 = 99.

99+ 1 = 100.

That one added to the 99 is the newcomer bird.
