There are 40 girls in a girls hostel. At a night all of them were suffering from sleeplessness, so they went to their warden and put their problem. After listining their problem, warden wrote on black board and a digit under each letter as under: S L E E P N I G H T 0 1 2 3 4 5 6 7 8 9 Then the warden asked to each girl to make a three digit number taking above digits (no repeated digit). Then the girls were asked to reverse the number and get the difference to original and reversed numbers. Again the resultent figure was asked for reversed and to be added to the resultant figure. The final result was asked to be multiplyed by the number of girls in the hostel i.e. 40. Lastly warden told that the result of multiplication is the solution of their proble, please convert the digits into the numbers. For sake of convinience the whole procedure is as under: chooser three number digit number = abc reverse of the number is = cba difference (substract lower one form the greator one) = def reverse of the number is = feg Total of above two = wxyz Total (wxyz) multiplyed by 40 = ????? Do it yourself to know the solution and convert the digits into the letter as shown above, repeated again as under S L E E P N I G H T 0 1 2 3 4 5 6 7 8 9
