Total bags + girls * No. of bags with each girl = 7*7 = 49
Each bag has 7 big cat. Thus big cats = 49*7 = 343
Each big cat has 7 small cats.
Thus total cats = Big cats + small cats = 343 + (343*7) = 2744
Each cat has 4 legs. Total legs of all cats = 2744*4 = 10976
TOTAL LEGS = All cat legs + Girls Legs = 10976 + (7*2) = 10990
Hope, it is right.

10,990 is the answer
so 7 girls =14 legs
7 book bags with 7 cats in each =49 cats per girl, times 7 girls =343 cats total, with 4 legs each= 1372 legs + 14 legs =1386 legs.
then each cat has 7 kittens. so 343 cats times 7 kittens= 2401 kittens total, each with four legs =9604 legs.
so 9604 kitten legs + 1386 girls and cats legs =10990 legs
so the answer is 10,990 legs total.
