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.
