Charges are kept at different position of cube, pick out the correct statement among the following 

Six identical charges q are placed at each corner and one more identical charge q kept      at center of the cube then net flux through the cube is $\frac{9}{5}\frac{q}{{\epsilon }_0}$

q charge is placed on one corner of cube then net flux through the cube is $\frac{7}{8}\frac{q}{{\epsilon }_0}$

Three identical charge +q each kept on one corner, on one face and on one side of cube respectively then net flux through the cube is  $\frac{7}{8}\frac{q}{{\epsilon }_0}$

q charge is uniform distributed on one side of a cube then net flux through the cube is  $\frac{7}{8}\frac{q}{{\epsilon }_0}$
