1) Man's wife. = 1
2) Man's 4 son's wives. = 4
3) Man's daughter. = 1
4) 4 son's has each one daughter. = 4

Let the amount collected be 'A'
Then, from the given conditions,
A x 110/100 x 90/100 = 7920

A = 7920/0.99
=> 8000

(100-x)%  of 88% of 8400 = 6896

=> 100-x10088100x8400 = 6896

=> x = 6.709%
