Q A speaks truth in 75% cases and B in 80% cases. In what percentage of cases are they likely to contradict each other,narrating the same incident ?
A : 35% cases...
Answer is given considering 2 situations :
1) when A speaks truth and B lies
2) when A lies and B speaks truth
I believe there should be another case also :
3) when both A and B lie.
Plz help

They are asking for contradiction cases : if both lying then they are on same platform and not contradicting . so only 2 cases would be there..
