Answer (official key): B

Solution

  • (1) Zebra and giraffe are separate kinds inside animals: Q (two disjoint circles in a big one).
  • (2) A person can be any combination of director, producer and actor: R (three overlapping circles).
  • (3) Word ⊂ sentence ⊂ novel: S (nested circles).
  • (4) Pianist and guitarist overlap, both inside instrumentalist: P.

Q10 · General Aptitude · MCQ · 2 marks

In the triangle PQR, the lengths of PT and TR are in the ratio of 3:2.

ST is parallel to QR. Two semicircles are drawn with PS and PQ as diameters, as shown in the figure.

Which one of the following statements is true about the shaded area PQS?

Note: The figure shown is representative.

Figure for GATE 2025 EE question 10 (Spatial Aptitude)

  • (A)
    The shaded area is 169\frac{16}{9} times the area of the semicircle with the diameter PS.
  • (B)
    The shaded area is equal to the area of the semicircle with the diameter PS.
  • (C)
    The shaded area is 149\frac{14}{9} times the area of the semicircle with the diameter PS.
  • (D)
    The shaded area is 1425\frac{14}{25} times the area of the semicircle with the diameter PQ.

Answer (official key): A

Solution

ST∥QRST \parallel QR gives PSPQ=PTPR=35\frac{PS}{PQ} = \frac{PT}{PR} = \frac{3}{5}. Areas scale with the square of the diameter: shaded=semicircle(PQ)−semicircle(PS)=(259−1)semicircle(PS)=169 semicircle(PS)\text{shaded} = \text{semicircle}(PQ) - \text{semicircle}(PS) = \left(\frac{25}{9} - 1\right)\text{semicircle}(PS) = \frac{16}{9}\,\text{semicircle}(PS)

    GATE 2025 EE question 39 (Electric Circuits), option C
  • (D)
    GATE 2025 EE question 39 (Electric Circuits), option D

Answer (official key): C

Solution

With RCRC much longer than the period, the RC low-pass acts as an integrator. The ±1 V square wave becomes a small triangular wave centred at 0, far below ±1 V: option (C).

Q51 · Electromagnetic Fields · MSQ · 2 marks

Let aR\boldsymbol{a_R} be the unit radial vector in the spherical co-ordinate system. For which of the following value(s) of nn, the divergence of the radial vector field f(R)=aR1Rn\boldsymbol{f(R)} = \boldsymbol{a_R}\dfrac{1}{R^n} is independent of RR?

  • (A)
    −2
  • (B)
    −1
  • (C)
    1
  • (D)
    2

Answer (official key): B, D

Solution

∇⋅f=1R2ddR(R2−n)=(2−n)R−n−1\nabla\cdot\boldsymbol{f} = \frac{1}{R^2}\frac{d}{dR}\left(R^{2 - n}\right) = (2 - n)R^{-n-1} This is independent of RR when n=−1n = -1 (value 3) or n=2n = 2 (value 0).

Q53 · Calculus · Numerical · 2 marks

Let (x,y)∈R2(x, y) \in \mathbb{R}^2. The rate of change of the real valued function,

V(x,y)=x2+x+y2+1V(x, y) = x^2 + x + y^2 + 1

at the origin in the direction of the point (1,2) is ________ (round off to the nearest integer).

Answer (official key): 0 to 1

Solution

∇V=(2x+1,2y)=(1,0)\nabla V = (2x + 1, 2y) = (1, 0) at the origin, and the unit direction is (1,2)5\frac{(1, 2)}{\sqrt{5}}. The rate is 15≈0.45\frac{1}{\sqrt{5}} \approx 0.45, which rounds to 0 (official range 0 to 1).

Questions about GATE 2025 EE

How many questions are in the GATE 2025 EE paper?

65 questions for 100 marks: 10 General Aptitude questions worth 15 marks and 55 Electrical Engineering questions worth 85 marks. By type, there were 42 MCQs, 4 MSQs, 19 numerical answer (NAT) questions. The paper lasted 3 hours.

Is there negative marking in GATE 2025 EE?

Yes, for MCQs only. A wrong MCQ answer costs one-third of its marks (−⅓ for a 1-mark question, −⅔ for a 2-mark question). MSQ and numerical (NAT) questions have no negative marking, and an MSQ earns marks only when every correct option is chosen.

Which topics carried the most marks in GATE 2025 EE?

Outside General Aptitude, the biggest topics were Power Electronics (10 marks), Signals and Systems (9 marks), Control Systems (9 marks). The full topic-wise split is in the table on this page.

Were any GATE 2025 EE questions awarded marks to all?

No. Every question was graded with the answer in the official key.

Where does this GATE 2025 EE answer key come from?

From the official answer key published by IIT Roorkee, which organised GATE 2025. Range answers for numerical questions and questions with more than one accepted answer are kept exactly as the key gives them.
