The average of twelve numbers is 42. The average of the last five numbers is 40 and that of the first four numbers is 44. The 6th number is 6 less than the fifth and 5 less than the 7th number. The average of the 5th and the 7th numbers is: बारह संख्याओं का औसत 42 है | अंतिम पांच संख्याओं का औसत 40 तथा पहली चार संख्याओं का औसत 44 है | छठी संख्या पाँचवीं से 6 कम है तथा 7वीं संख्या से 5 कम है | 5वीं और 7वीं संख्या का औसत है :
