A company manufactures car batteries of a particular type. The lives (in years) of 40 such batteries were recorded as follows: 2.6 3.0 3.7 3.2 2.2 4.1 3.5 4.5 3.5 2.3 3.2 3.4 3.8 3.2 4.6 3.7 2.5 4.4 3.4 3.3 2.9 3.0 4.3 2.8 3.5 3.2 3.9 3.2 3.2 3.1 3.7 3.4 4.6 3.8 3.2 2.6 3.5 4.2 2.9 3.6 Construct a grouped frequency distribution table for this data, using class intervals of size 0.5 starting from the interval 2 - 2.5.

A word is represented by only one set of numbers as given in any one of the alternatives . The sets of numbes given in the alternatives are represented by two classes of alphabets as shown in the given two matrices . The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix -II are numbered from 5 to 9 . A letter from these matrices can be represented first by its row and next by its column for example P can be represented by 22, 75 etc, and L can be represented by 20 , 78 etc . Similarly you have to indentify the set for the word WATCH .

A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-l are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example, 'C' can be represented by 11, 67, etc., and 'E' can be represented by 22, 58, etc. Similarly, you have to identify the set for the word "FOLK".
