Case 1:Annie truth Others lie

Case 2:Fanny truth others lie

Case 3:Danny truth others lie
















4. 15

let total bars given to sister be x
so 1/2 to mother and 1/2 more to father ie x/2 + 1/2
so remaining = x- ( x/2 + 1/2 ) =x/2- 1/2
then 1/2 of the remaining and 1/2 more to dog

1/2 (x/2 - 1/2 )+ 1/2 = x/4 - 1/4 + 1/2 = x/4 + 1/4

so remaining = x/2 - 1/2 - ( x/4 + 1/4 )

= x/2- 1/2 - x/4 - 1/4

=x/4 - 3/4

x/4 - 3/4 =3

1e... x/4=3+ 3/4

x= (15/4 ) *4


49th day doubles each day

8.a. 63 b.231
