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.

Solutions:
Answer.1.C
Let their present ages be 6x, 9x and 11x years respectively.
Then, (6x – 10) + (9x – 10) + (11x – 10) = 48
26x = 78
x = 3
Their present ages are 6x = 18 years, 7x = 21 years and 9x = 27 years respectively.
hence, Required Average = (18+ 21+ 27)/3 = 66/3 = 22 years
Answer.2.B
(64 x 36) womens can complete the work in 1 day.
1 day’s work of 1 Woman’s = 1/2304
(54 x 21) Men can complete the work in 1 day.
1 day’s work of 1 Man‘s = 1/1134
therefore,
Req. ratio = 1/1134 : 1/2304 = 128:63
Answer.3.D
A + B + C = (64 x 3) = 192 …. (i)
A + B = (54 x 2) = 108 …. (ii)
B + C = (58 x 2) = 116 ….(iii)
Adding (ii) and (iii), we get: A + 2B + C = 224 …. (iv)
Subtracting (i) from (iv), we get : B = 224-192= 32.
hence, B’s weight = 32 Kgs.
Answer.4.A
Let tap C will empty the tank in ‘t’ minutes
Here, X = 30, Y = 60 and Total time to fill tank = 50 minutes
C can empty the full tank in = (XYZ /YZ +ZX –XY) Minutes
= ( 30*60*50/ ( 60*50 + 30*50 -30*60)
= 90000/2700 = 10/3 Minutes
Answer.5.C
Speed of train from new Delhi to Moradabad (s1) = 60, 
Speed of train from Moradabad to new delhi (s2) = 80, 
T = time from 6 P.M. to 7 P.M. = 1 hr
Distance of meeting point from New delhi= S1 {( d +S2 t) / (S1 +S2)} km
= 60 {( 340 + 80X1) / (60+80)} = 180 km
Time of their meeting = {( d +S2 t) / (S1 +S2)}
{( 340 + 80X1) / (60+80)}
3 Hrs after 6 PM
i.e. 9:00 PM
Answer.6.B
Chintu’s 1 day’s work = 1/5 – ( 1/9 + 1/12) = (1/5 – 7 /36) = 1/180
hence, Ratio of their wages = Arun :Bimal :Chintu =1/9 : 1/12 : 1/ 180
= 20:15:1
hence,
Chintu’s Share=4800 * (1/36) = 133.33 Rs.
Answer.7.(D)
Let the original price to be Rs 100.
So he bought it at 10% discount ieRs 90 and 
sells it at 35% more than the original rate ieRs 135.
Actual profit is 135- 90=Rs 45
So % profit =45/90×100=50%
Answer.8.(A)
By the method of allegation
(15-x)/(x-10)=2/5
Or, 75- 5x=2x-20
Or, 7x=95
Or, x=13.57%
Answer.9.(E)
Let the present ages of Arnab and Sanjana be 13x and 17x years respectively.
?(13x-4)/(17x-4)=11/15
187x – 44=195x-60
195x-187x = 60-44
8x=16
x=2
Required ratio =(13×2+6):(17×2+6) =32 : 40 = 4 : 5
Answer.10.(A)
Let the required average age be x years.
80×15=15×16+25×14+40×x
40x=1200-240-350=610
hence, x=610/40=15.25 years
