Girls in residential college complain to Maths prof of lack of sleep.
Prof writes down the problem on the board
S L E E P N I G H T. He assigns a digit to each alphabet.
0 1 2 3 4 5 6 7 8 9
hE ASKS EACH GIRL STUDENT TO CHOOSE ANY 3 CONSECUTIVE NUMBERS (E.G 012, 345 ETC) AND REPEAT THE 3 DIGIT No. when in bed.
Next day he asks them to reverse the No chosen on day one and repeat the new number.
day 3 he asks them to subtract day 1 No from Day 2. 9ignore -ve sign) and repeat the new number in bed.
day 4 he asks them to reverse the day 3 No and repeat this number in bed.
Day 5 he asks the students to add day 4 and day 5 number and repeat this number in bed.
Day 6 he asks the class and enquires if the sleep problem solved. All the 40 girls reply negative.
Prof says the problem is compounded. So multiply the day five number by 40 and replace the digits by alphabets written on board, e.g 0 is S, 1 is L so on and so forth.
Got the answer?(try any)

All of the combinations u take always give u the same word. I guess the whole trick lies when u ask us to subtract the number of Day 1 from Day 2's. Because, even if u take any combination, when u subtract the number from its reverse it will always give u the number 198. And when u add 198 to 891 (its reverse) u will always get 1089. And when u multiply this by 40...u get 43560...erm...so u can decode it n see...
