The average of thirteen numbers is 80. The average of the first five numbers is 74.5 and that of the next five numbers is 82.5. The 11th number is 6 more than the 12th number and the 12th number is 6 less than the 13th number. What is the average of the 11th and the 13th numbers? तेरह संख्याओं का औसत 80 है | पहली पांच संख्याओं का औसत 74.5 और अगली पांच संख्याओं का औसत 82.5 है | 11वीं संख्या 12वीं संख्या से 6 अधिक है तथा 12वीं संख्या 13वीं संख्या से 6 कम है | 11वीं तथा 13वीं संख्याओं का औसत ज्ञात करें |

The average of twelve numbers is 55.5. The average of the first four numbers is 53.4 and that of the next four numbers is 54.6. The 10th number is greater than the 9th number by 3 but lesser than the 11th and 12th numbers by 2 and 3, respectively. What is the average of the 10th and the 12th numbers? बारह संख्याओं का औसत 55.5 है | पहली चार संख्याओं का औसत 53.4 है तथा अगली चार संख्याओं का औसत 54.6 है | 10वीं संख्या 9वीं संख्या से 3 अधिक है लेकिन 11वीं और 12वीं संख्याओं से क्रमशः 2 और 3 कम है | 10वीं और 12वीं संख्याओं का औसत ज्ञात करें |

This question is based on the following alphabet series. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z If the first 6 letters are written in reversed order, then the next 5 letters are written in reversed order and again next 6 letters are written in reversed order then which letter is in the middle between 7th letter from the left and 12th letter from the right? 1) G 2) T 3) H 4) U 5) None of these

The average of 12 numbers is 18.5. The average of first six numbers is 16.8 and that of the last seven numbers is 17.4. If the 6th number is excluded, then what is the average (correct to one decimal place) of remaining 11 numbers? 12 संख्याओं का औसत 18.5 है | पहली छः संख्याओं का औसत 16.8 है तथा अंतिम सात संख्याओं का औसत 17.4 है | यदि छठी संख्या को हटा दिया जाए, तो शेष 11 संख्याओं का औसत (एक दशमलव स्थान तक) क्या होगा ?
