let us arrange the letters of the word in ascending order[A,B,L,O,R,U] then according to dictionary l appears in the third section . if the word start with A then remaining 5 letter we can arrange in 5! ways . similarly if it starts with B then remaining 5 letters we can arrange in 5! ways total = 5!+5!=120+120=240. then 241th word is LABORU because R comes before U and the 242nd word is LABOUR therefore the word "LABOUR" appears in 242nd place
