Q(1-5) In the following questions two equations numbered I & II are given. You have to solve both equations and mark the option.

1. X² – 49√2X + 1200 = 0
Y² – 45√3Y + 1518 = 0
A. X > Y
B. X <Y
C. X ≥ Y
D. X ≤ Y
E. X = Y or relationship cannot be established
B. X <Y
Solution:
X = 24√2, 25√2 = 33.94, 35.35
Y = 23√3, 22√3 = 39.98, 38.10
Representing on number line we get X<Y

2. I. X²  + 15√2X + 112 = 0
II. Y²  + 13√2Y + 84 = 0
A. X > Y
B. X <Y
C. X ≥ Y
D. X ≤ Y
E. X = Y or relationship cannot be established
D. X ≤ Y
Solution:
X = -14/√2, -16/√2
Y = -12/√2, -14/√2 By comparison We get X ≤ Y

3. I. 6X² – 75√2X + 450 = 0
II.6Y² – 70√3Y + 588 =0
A. X > Y
B. X <Y
C. X ≥ Y
D. X ≤ Y
E. X = Y or relationship cannot be established
E. X = Y or relationship cannot be established
Solution:
X = 15/√2, 5√2 = 10.60, 7.07
Y = 7√3, 14/√3 = 12.12, 8.08

4. I. 12X² – 96X + 180 = 0
II. 6Y² – 20Y + 6 =0
A. X > Y
B. X <Y
C. X ≥ Y
D. X ≤ Y
E. X = Y or relationship cannot be established
C. X ≥ Y
Solution:
X = 15/3, 12/4 = 5,3
Y = 6/2, 1/3 = 3, 0.333

5. I. X² = 289
II.Y² – 34Y +289 =0
A. X > Y
B. X < Y
C. X ≥ Y
D. X ≤ Y
E. X = Y or relationship cannot be established
D. X ≤ Y
Solution:
X = 17, -17
Y = 17, 17

Q(6-10) Find the missing number in the number series.

1. 10, 22, 120, 1176, ?
A. 16440
B. 17240
C. 19840
D. 20040
E. None
C. 19840
Solution:
(10+1³)*2 = 22
(22+2³)*4 = 120
(120+3³)*8 = 1176
(1176+4³)*16 = 19840

2. 12, 13, 44, 423, ?
A. 6523
B. 6660
C. 6960
D. 6704
E. None
D. 6704
Solution:
12*1² + 1³ = 13
13*2² – 2³ = 44
44*3² + 3³ = 423
423*4² – 4³ = 6704

3. 1, 4, 9, 25, 69.5, ?
A. 219.5
B. 220.5
C. 221
D. 222.5
E. None
A. 219.5
Solution:
1*1+2+1 = 4
4*1.5+4- 1 = 9
9*2 +6 +1 = 25
25*2.5 +8 -1 =69.5
69.5*3 +10+1 = 219.5

4. 365, 365, 372, 346, 409, ?
A. 285
B. 326
C. 378
D. 426
E. None
A. 285
Solution:
365 – 1³ + 1  = 365
365 + 2³ – 1 = 372
372 – 3³ + 1 = 346
346 + 4³ – 1 = 409
409 – 5³ + 1 = 285

5. 2, 2, 3, 5.5, 12,?
A. 29
B. 30
C. 31
D. 31.5
E. None
C. 31
Solution:
2*0.5 +1 = 2
2*1+1 = 3
3*1.5 +1 = 5.5
5.5*2 +1 = 12
12*2.5 +1 = 31
