The number of birds on each of the islands x and y remains constant from year to year; however, the birds migrate between islands. after one year, 20 percent of the birds on x have migrated to y, and 15 percent of the birds on y have migrated to x. ? if the total number of birds is 14, 000, how many birds are on island
the options given area) 2,800.b) 6,000.c) 6,788.d) 7,212.
e) 8,000.

Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Total number of birds = 14000

Let the number of birds on X be 'x'.

Let the number of birds on y be 14000-x

After one year, 20 percent of the birds on X have migrated to Y, and 15 percent of the birds on Y have migrated to X.

but The number of birds on each of the islands X and Y remains constant from year to year.

So, the equation would be

Hence, there are 6000 birds on island X.

Hence, Option 'b' is correct.
