Answers:
Q1 – (4)
Let Bhavika and Rita working together
can finish a job in x days.
Then, in 1 day they will complete = 1/x work
Bhavika working alone do in 1 day = 1/(x+8) work
Rita working alone will do in 1 day = 1/(x+9/2) work
So, 1/(x+8) + 1/(2x+9) = 1/x
=> [(2x+9) + 2(x+8)]/[(x+8)(2x+9)] = 1/x
=> x = 6days
Q2 – (2)
According to Question 
M1 x D1 x T1 x W2 = M2 x D2 x T2 x W1
36 x 6 x 10 x 1200 = 10 x D2 x 8 x 1200
D2 = 36 x 6 x 10 x 1200 / 10 x 9 x 1200 = 27days
Q3 – (3)
Let the speed of the car be x km/h
So, Speed of train = x * 1.2x = 6x / 5 km/h
So, 5/6x * 75 + 25/(2*60) = 75/x
= 75*2*60/6*25 = 60km/h
Q4 – (1)
Let the length of each train be x mtr
Then, total distance covered = (x + x) = 2x mtr
Relative Speed = (46 – 6) = 10 km/h = 10*5/18 m/s
Given (time) 36 = 2x * 18/50
Q5 – (2)
According to question, S.I. on Rs. 100 at 10% for six months 
=(100*10*6)/(100*12) = Rs. 5
Principal for next six months = Rs. 105
SI = 105*10*6/100*12 = Rs. 5.25
Total interest = Rs. 10.25
Q6 – (2)
The series is 1² x 2 = 2, 2² x 3 = 12, 3² x 4 = 36, 4² x 5 = 80 and so on.. Hence, 81 should be replaced by 80.
Q7 – (1)
The series is 1 x (2+3) = 5, 2 x (3+4) = 14, 3 x (4+5) = 27 and so on..
Hence, 16 should be replaced by 14
Q8 – (3) 
The series is 3² – 2² – 1² = 4, 4² – 3² – 2² = 3 and so on..
Hence, 2 should be replaced by 3.
Q9 – (4)
The series is 10² + ² + 0² = 101, 11² + 1² + 1² = 123, 12² + 1² + 2² = 149 and so on..
Hence, 218 should be replaced by 213
Q10 = (2)
The series is x 2 + 3, x 2 + 5, x 2 + 7, x 2 + 9, x2 + 11 and so on..
Hence, 45 should be replaced by 47.

(1) if the inference is ‘definitely true’, i.e. it properly follows from the statement of the given facts. 
(2) if the inference is ‘probably true’ though not ‘definitely true’ in the light of the given facts. 
(3) if the ‘data are inadequate’, i.e. from the given facts you cannot say whether the inference is likely to be true or false. 
(4) if the inference is ‘probably false’, though not ‘definitely false’ in the light of the given facts. 
(5) if the inference is ‘definitely false’, i.e. it cannot possibly be drawn from the given facts or it contradicts the given facts.
Between 2002-03 and 2006-07, Indian economy grew annually at 8.7% led by the services sector at 9% per year. In 1990, India’s share of services, at 40% of GDP, was consistent with the average for low income countries, considering India’s per capita income. By 2001, its share in India’s GDP, at 50% of the GDP was five percentage points higher, compared to the average for low-income countries. Economic reforms that energized the private corporate sector and technological changes that opened up new vistas in telecommunications, IT and outsourcing are believed to be responsible for the impressive performance. However, the services led growth remains a puzzle at a low per capita income, with 55% of the work force still engaged in agriculture, and when agriculture decelerated and industry stagnated – defying a styled fact in economics.
Question.8. 
Inference:
Share of services sector in India’s GDP has crossed the half way mark in early 2000.
Directions for question 9: In making decision about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those which are both important and directly related to the question. ‘Weak’ arguments are those which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question.
The question given below is followed by two arguments numbered I and II. You have to decide which of the argument is a ‘strong’ argument and which is a ‘weak’ argument.
Give answer (1) if only argument I is strong.
Give answer (2) if only argument II is strong.
Give answer (3) if either argument I or II is strong.
Give answer (4) if neither argument I nor II is strong.
Give answer (5) if both arguments I and II are strong.
Question.9.Statement:
Should the Government substantially increase the tax on water supplied to the farmers for the irrigation of their fields?
Arguments :
I. No, the farmers are even otherwise hard pressed to meet their expenditure for cultivating their lands.
II. Yes, the rich farmers make huge profits, as the water tax for irrigation is considerably lower than otherwise.

Solutions:
Solutions for Question (1 – 5):

Answer.1. 1
Answer.2. 4
Answer.3. 4
Answer.4. 3
Answer.5. 2
Solutions for Question (6 – 10):
Answer.6. 5; Option (5) is the correct answer because the statement mentions that the BPOs in India are being ‘challenged by’ the American accent of their customers, which means that Indian employees find its difficult to understand their customer’s language because of their American accent.
Answer.7. 4; The problem mentioned in the statement is decoity and looting in passenger trains. Course of action I does not follow because it is impracticable to arrange for so many policemen. Course of action II also does not follow because training each and every passenger of every passenger train is also not feasible. Hence, option (4) is the correct answer.
Answer.8. 3; Data is inadequate.
