6 months ago, there were 176÷2= 88 rabbits
12 months ago 88÷2= 44 rabbits
18 months ago 44÷2= 22 rabbits
24 months ago= 22÷2= 11 rabbits
30 months ago= 11÷2= 5.5
27 months ago= 8.75 (Taking middle no. btwn 5.5 & 11)
25.5 months ago= 9.25 (Taking middle no btwn 8.75 & 11)
Therefore, there were 10 rabbits 25 months ago.
