Dally Challenge 2 April
A municipality was conducting a test for pathogens in water across a oty. There are 16 samples
of water from tanks in different parts of the city, but only 8 testing kits. The lab technician
decided to pool together the water samples into a bottles labeled A to H.
Tank 1 - Bottle B,D,F,H
Tank 2 - Bottle B,D,F,G
Tank 3 - Bottle B,D,E,H
Tank 4 - Bottle B,D,E,G
Tank 5 - Bottle B.CF,H
Tank 6- Bottle B,C,F,G
Tank 7 - Bottle B,C,E,H
Tank & - Bottle B,C,E,G
Tank 9 - Bottle A,D,FH
Tank 10 - Bottle A,DF,G
Tank 11 - Bottle A,DEH
Tank 12- Bottle ADEG
Tank 13 - Bottle A,C, FH
Tank 14 - Bottle A,C,F,G
Tarik 15 - Bottle ACEH
Tank: 16 - Bottle A,C,E,G
If water from a tank has the pathogen, then each bottle containing a sample from it will test
positive
If a bottle test positive, one of the tanks whose water samples were posted into it contains the
bathogen, if a bottle tests negative, then none of the tanks whose water samples were mixed
into the bottle has the pathogen.
If bottle C tests positive and bottle E, H, and A test negative, which tank had the pathogen?​

Answer 1

Answer :

Tank 6- Bottle B,C,F,G and Tank 14 - Bottle A,C,F,G has the pathogen
