Three persons Shruti, Vihaan and Vishi gave the following statements about Anu's sweater.
Shruti said, “She is either wearing red or green.”
Vihaan said, “She is wearing red.”
Vishi said, “She is neither wearing red nor green.”
Of these three, only one person is wrong.
Which colour sweater is Anu wearing?
Vishi's statement contradicts Shruti's and Vihan's statements, so only Vishi's statement can be false.
This means Vihan's statement, "She is wearing red," is true. So, Anu's dress is red.
