Check Paper wise Syllabus for GATE 2018:

The  Paper wise Syllabus for GATE 2018 was presented below but before that I want to show you what is the proforma of Verbal Ability and Numerical Ability with the help of some sample questions.

Verbal Ability: English grammar, sentence completion, verbal analogies, word groups, instructions, critical reasoning and verbal deduction.

Numerical Ability: Numerical computation, numerical estimation, numerical reasoning and data interpretation.

Sample Questions:

Verbal Ability

Q.1. Choose the appropriate answer to complete the following sentence:

To those of us who had always thought him timid, his ——— came as a surprise.

(A) intrepidity (B) inevitability (C) inability (D) inertness

Ans. (A)

Q.2. Read the following paragraph :

“The ordinary form of mercury thermometer is used for temperature ranging from –40o F to 500o F. For measuring temperature below –40o F, thermometers filled with alcohol are used. These are, however, not satisfactory for use in high temperatures. When a mercury thermometer is used for temperature above 500o F, the space above the mercury is filled with some inert gas, usually nitrogen or carbon dioxide, placed in the thermometer under pressure. As the mercury rises, the gas pressures is increased, so that it is possible to use these thermometers for temperatures as high as 1000o F.”

With what, besides mercury, would a thermometer be filled if it was designed to be used for measuring temperature of about 500o F?

(A) Pyrometer (B) Inert gas (C) Iron and brass (D) Gas

Ans. (B)
