i.e. 12 ways. Therefore total ways for this particular case = 2×12=24 ways
2. Case 2 : Both sister sat by the window seat , it can be achieved in 2 ways. Other members can be accommodated in 2×2×1 = 4 ways.
Therefore total ways for this case= 2×4 = 8.
<em>Total ways in which it can be done = 24+8 =32.</em>
