Answer 1

We Know :-
Each Gatekeeper Take = -1/2 Cake
Gatekeeper Gift Back = +1/4 Cakt
Total Cake Taken By 7 Gatekeeper = 3 Cake & Half
Gatekeeper Gifted Back Cake = 1 Cake & 3/4 Cake...
He Need To Carry 1 Cake & 3/4 Cake For Gatekeeper & 2 Cake For Friends
He Need To Carry = 2+1+3/4 ==> 3 Cake & 3/4 Part Of Cake...

I Hope You Understood :)
