In the following figure, square represents athletes, triangle represents engineers, circle represents fathers and rectangle represents entrepreneurs. Which set of letters represents athletes who are either entrepreneurs 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 S to 9. A letter from these matrices can be represented first by its row and next by its column, for example 'K' can be represented by 32, 01 etc and 'R' can be represented by 79, 99 etc. Similarly, you have to identify the set for the word 'GLUE'.

Which of the following statement(s) is/are CORRECT?
I. Metallic oxides are said to be basic oxides.
II. Non-metallic oxides are basic in nature.
III. All acids have similar chemical properti es.

I. The apparent displacement of a pencil, partly immersed in water.
II. Sun appears before the sunrise.
III. Sky appears blue.

Low frequency supply is necessary for direct core type induction furnaces because

A locomotive exerts a tractive effort of 35,300 N in hauling a train at 48kmph on the level track. If the motor is to haul the sametrain on a gradient of 1 in 50 and thetractive effort required is 55,180N, determine the power delivered by the locomotiveif it is driven by (i) dc series motors (ii) induction motors.

If the synchronous motor, properly synchronized to the supply is running on no load andis having negligible loss then
