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.
