In the following figure, square represents Artists, triangle represents Military officers, circle represents Collectors, and rectangle represents Fathers. Which set of letters represents collectors who are either military officers or fathers ?

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-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 'H' can be represented by 21, 43 etc and 'R' can be represented by 96, 87 etc. Similarly, you have to identify the set for the word 'POEM'.

Which one of the following is not a feature of monopolistic competition?

Which of the following statements are CORRECT ?
I. Change in magnetic field produces induced current.
II. Flow of current in a conductor produces magnetic field.
III. Magnetic field related to coil can be produced by motion between conductor and coil.
