07. The overwhelming number of people infected with rabies in India has been flagged by the World
Health Organization as a source of concern. It is estimated that inoculating 70% of pets and stray
dogs against rabies can lead to a significant reduction in the number of people infected with rabies.
Which of the following can be logically inferred from the above sentences?
(A) The number of people in India infected with rabies is high
(B) The number of people in other parts of the world who are infected with rabies is low.
(C) Rabies can be eradicated in India by vaccinating 70% of stray dogs
(D) Stray dogs are the main source of rabies worldwide

07. The overwhelming number of people infected with rabies in India has been flagged by the World
Health Organization as a source of concern. It is estimated that inoculating 70% of pets and stray
dogs against rabies can lead to a significant reduction in the number of people infected with rabies.
Which of the following can be logically inferred from the above sentences?
(A) The number of people in India infected with rabies is high
(B) The number of people in other parts of the world who are infected with rabies is low.
(C) Rabies can be eradicated in India by vaccinating 70% of stray dogs
(D) Stray dogs are the main source of rabies worldwide
07. Ans: (A)
Sol: Only option ‘A’ can be logically inferred from the information provided in the argument.
08. A flat is shared by four first year undergraduate students. They agreed to allow the oldest of them
to enjoy some extra space in the flat. Manu is two months older than Sravan, who is three months
younger than Trideep. Pavan is one month older than Sravan. Who should occupy the extra space
in the flat?
(A) Manu  (B) Sravan   (C) Trideep    (D) Pavan
08. Ans: (C)
Sol: Manu age = sravan age + 2 months
Manu age = Trideep age – 3 months
Pavan age = Sravan’s age + 1 month
From this Trideep age > Manu > Pavan > Sravan
? Trideep can occupy the extra space in the flat
09. Find the area bounded by the lines 3x + 2y = 14, 2x –3y = 5 in the first quadrant.
