Q2: Novelist has white hair
Q3: Dr. Gold Has bLACK HAIR

If THE LADY WITH BLACK HAIR IS SPEAKING THEN WE KNOW IT CAN NOT BE THE NOVELIST WHOSE NAME IS BLACK. SHE IS SPEAKING TO PROFESSOR WHITE SO THE PROFESSOR CAN NOT HAVE BLACK OR WHITE. SO IF THE PROFESSOR HAS GOLD HAIR AND THE NOVELIST CANNOT HAVE BLACK HAIR, THE NOVELIST HAS WHITE HAIR AND THAT LEAVES BLACK HAIR FOR THE DOCTOR.

Solution:
Q1: Pr.White's hair is gold
Q2: E.Black's hair is white
Q3: DrGold's hair is black

Prof. White's hair couldn't be white because none of the colors in their last names could be their hair color. She was talking to the lady with black hair, so her hair couldn't be black. It was gold. E.Black's hair couldn't be black or gold, so it was white. Dr Gold's hair couldn't be gold or white, so it was black.

Logesh from U.S.A
Grade: 6 Age: 11 School:
Solution:
Q1: Dr.Helen Gold has black hair.
Q2: Mary White has gold hair.
Q3: Elanor Black has white hair.

It said that they can not have the last name as a color. Then the person who said that fact said they had black hair and Mary White replied. So we know it can't be Elanor Black because of her last name and it can't be Mary white because she was the one that replied. So it was Helen Gold. Now black is eliminated. Mary White can't be white so it has to be gold. Now Elanor Black only on choice which is white.
