In 'CATRACT' the distinct set of letters is {C,A,T,R} while in "TRACT" the distinct set of letters is {T,R,A,C} . So, { C,A,T,R}={T,R,A,C} are equal. Hence set of letters needed to spell both the words are equal.

CATARACT : distinct letters are { C,A,T,R} TRACT : distinct letters are {T,R,A,C} HENCE {C,A,T,R}={T,R,A,C} both the sets have same distinct letters
