Q4. The dawn of the 21st century witnessed the melting glaciers oscillating between giving too much and too little to billions of people who depend on them for fresh water. The UN climate report estimates that without deep cuts to man-made emissions, at least 30% of the Northern Hemisphere’s surface permafrost could melt by the end of the century. Given this situation of imminent global exodus of billions of people displaced by rising seas, nation-states need to rethink their carbon footprint for political concerns if not for environmental ones.

Which one of the following statements can be inferred from the given passage?

(A) Nation-states do not have environmental concerns

(B) Nation-states are responsible for providing fresh water to billions of people

(C) Billions of people are responsible for man-made emissions

(D) Billions of people are affected by melting glaciers

Ans: (D) Billions of people are affected by melting glaciers

Q5. There are multiple routes to reach from node 1 to node 2, as shown in the figure below:

The cost of the travel on an edge between two nodes is given in rupees. Nodes, ‘a’, ‘b’, ‘c’, ‘d’, ‘e’ and ‘f’ are toll booths. Which is the cheapest route from node 1 to node 2?

(A) 1-a-c-2

(B) 1-f-b-2

(C) 1-b-2

(D) 1-f-e-2

Ans: (B) 1-f-b-2

Solution: (A) Cost=200 + 100 + 100 = 400

(B) Cost= 100 + 0 + 200 = 300

(C) Cost = 300 + 200 = 500

(D) Cost = 100 + 100 + 200 = 400

So minimum cost is of (B)

Q6 – Q10 carry two marks each.

Q7. If P =3, R=27, T=243, then Q+S=______

(A) 40

(B) 80

(C) 90

(D) 110

Ans: (C) 90

Solution : P=3, R= 27, T=243

Sequence is: P=3


R=3 * 3 * 3=27

S=3 * 3 * 3 * 3 =81

Q + S= 9 + 81 = 90

Q8. The figure below shows an annular ring with outer and inner radii as b and a, respectively. The annular space has been painted in the form of blue colour circles touching the outer and the inner periphery of annual space. If maximum n number of circles can be painted, then the unpainted area available in annular space is _______

(A) Π [(b2-a2) – n/4(b-a)2]

(B) Π [(b2-a2) – n(b-a)2]

(C) Π [(b2-a2) + n/4(b-a)2]

(D) Π [(b2-a2) + n(b-a)2]

Ans: Π [(b2-a2) – n/4(b-a)2]

Q9. Two straight angles are drawn perpendicular to each other in X-Y plane. If α and β are the acute angles the straight lines make with the X- axis, then α+ β is _____

(A) 60°

(B) 90°

(C) 120°

(D) 180°

Ans: (B) 90°

In a triangle, sum of all three angles is 180°

Q10. The total revenue of a company during 2014-2018 is shown in the bar graph. If the total expenditure of the company in each year is 500 million rupees, then the aggregate profit or loss(in percentage) on the total expenditure of the company during 2014-2018 is ______

(C) 20% profit

(D) 20% loss

Ans: (C) 20% Profit

Solution: Total expenditure during each year =500 million rupees
Total expenditure for 5 years =500×5=2500 million rupees

  • Revenue in 2014=500 million rupees
  • Revenue in 2015=700 million rupees
  • Revenue in 2016=800 million rupees
  • Revenue in 2017=600 million rupees
  • Revenue in 2018=400 million rupees

Total revenue =500+700+800+600+400=3000 million rupees
Profit =3000−2500=500 million rupees
Profit percentage =(500/2500)×100=20%.
