The Graduate Aptitude Test in Engineering (GATE) is an examination held in India that primarily assesses a student’s understanding of various undergraduate engineering and science subjects in preparation for admission to a master’s program and employment in the public sector. GATE is administered on behalf of the National Coordination Board – GATE, Department of Higher Education, Ministry of Education (MoE), Government of India, by the Indian Institute of Science and seven Indian Institutes of Technology in Roorkee, Delhi, Guwahati, Kanpur, Kharagpur, Chennai (Madras), and Mumbai (Bombay).
A candidate’s GATE score reflects his or her relative level of performance. The score is used to determine admission to various post-graduate education programs in Indian higher education institutions, with funding provided by the Ministry of Human Resource Development and other government agencies.

Q13 If you consider the number of states in minimal DFA and NFA using the regular expression r = (11 + 111)* over = 0 and 1, you get:
a). DFA – 4; NFA – 3; DFA – 4; NFA – 3; DFA – 4;
b). DFA – 3; NFA – 3; DFA – 3; DFA – 3; DFA – 3;
c). DFA (3), NFA (4)
d). DFA – 4; NFA – 4; DFA – 4; NFA – 4; DFA – 4;
Answer: a) DFA – 4, NFA – 3 is the correct answer.

Q14 If G is the CFG, r is the total number of rightmost derivations, l is the total number of leftmost derivations, and P is the total number of parse trees, then r, l, and P must be computed for each string separately.

a). r ≤ P ≥ l
b). r = P = l
c). r ≥ P ≤ l
d). None
Answer: (b) r = P = l.
Thus, the correct answer to the following is r = P = l
Q15 Consider the case of a G ambiguous grammar and its D disambiguated counterpart. Which of these statements is true if the language recognized by these two grammars is denoted by L(G) and L(D)?
a). L (D) = L (G)
b). L (D) ⊂ L (G)
c). L (D) is empty

Q16 Which of these refers to the water content of the soil, which represents any liquid-plastic state boundary?
a). liquid limit
b). plastic limit
c). shrinkage limit
d). none of the above
Answer: (a) liquid limit.
The liquid limit is the point at which the soil begins to behave like a liquid. The liquid limit is determined by placing a clay sample in a standard cup and using a spatula to create separation (groove). The cup is dropped until the separation is no longer visible.

b). does not change
c). decreases at first then increase
d). declines
Answer (d) decreases is the correct answer.
In a consolidated drained test on a very normal consolidated day, the total volume of the available soil sample during the shearing decreases

b)Increased by 55%
c)Decreased by 55%
d)Increased by 50%
Answer (d).
As a result, it is decreased by 50%.
Q20 The maximum core flux density of a transformer will increase by 50% when the applied voltage is increased by 50% and the frequency is reduced by 50% (assuming the magnetic circuit remains unsaturated).
- a) Increase the value to three times the original.
- b) Increase the value to twice the original value
- c) Increase the value to 1.5 times the original valued
- d) Retains the same value as before.
Answer (a).
The maximum core flux density of a transformer will increase by 50% when the applied voltage is increased by 50% and the frequency is reduced by 50% thus it increases the value to three times the original
