Answers:
1)b   2)a   3)b   4)d   5)b   6)a   7)b   8)c   9)b   10)c   11)b    12)b   13)e   14)e   15)e      
Solutions:
1. B) Total = (21+18) + (12+6) + (20+27) +( 34+41) + (17+10 ) = 39+18+47+75+27 = 206
2. A) 2014 = 104; 2015 = 102; 2016 = 138
3. B) Required % = 50 – 34/34 × 100 = 16/34 × 100 = 47% (Approx.)
4. D) Maharashtra Average = (17 + 10 + 12)/3 = 39/3 = 13
5. B) New Delhi 2016 = 50
Maharashtra 2014 = 17
Diff = 50 – 17 = 33
6. A) Length = x; Breadth =y
xy – (x-5)(y+3) = 9
3x – 5y – 6 = 0 —(i)
(x+3)(y+2) – xy = 67
2x + 3y -61 = 0 —(ii)
solving (i) and (ii)
x = 17m ; y = 9m
7. B) No of passengers = 15*10 = 150
15+14+13+12+11+10+9+8+7 = 99
150 -99 = 51
8. C) Boys = 4x and girls = 7x
Ratio = 4x*125/100 : 7x*115/100 = 100:161
9.  B) Pipe A’s work in % = 100/10 = 10%
Pipe B’s work in % = 100/20 = 5%
Pipe C’s work in % = 100/40 = 2.5%
All of them are opened for 2 hours + after 2 hours, tap C is closed + After the 4th hour, tap B is also closed = 100
=> (10+5+2.5)*2 + (10+5)*2 + X = 100
=> 35 + 30 + work by tap A alone = 100
=> work by tap A alone = 100-65 = 35%
10. C) P*(1 + 4/100)^8 = (3903 – P)*(1 + 4/100)^10
11. B) From equation (i) b = ¾ r
From equation (ii) r = a2 = 144 => a = 12
Therefore only (ii) is sufficient to answer the question
12. B) 3T + 2C = ?
From Equation II …..
2 Table = 1 Chair = 500
3t = 250× 3 = 750
2c = 500 × 2 =1000
3t + 2c = 750 + 1000 = 1750
13. E) S = 8500 + Amit
Rahul's monthly income = 3.5 thousand
Amit's monthly income = 3.5 × 2 = 7.0 thousand
Then, Jyoti monthly income = 8500 + 7000 = 15500
So (E) is the correct option
14. E)
15. E)
