If 4/(1 + 3/x) = 1
=> 4x/(x+3)=1
=> 4x=x+3
=>3x = 3
=>x = 1

Now, number of even places = 4.
Number of girls to occupy the even places = 4.
Even places can be filled = P (4, 4) ways.
Number of boys = 4.
The remaining 4 places can be filled by 4 boys = P (4, 4) ways

now, any expression in which we have 4 at the denomin... |

Hence He can go in 24 ways.
Since we can not come back in the same bus that he used for travelling,
we can return in 23 ways.
Total number of ways = 24 x 23 = 552
