b) if x < y
c) if x ≥ y
d) if x ≤ y
e) if x = y or relationship between x and y can’t be established





Solutions:
1. C)
Series I        19       26         46          91           173                     ?
Series II  :        7                  20               45                 82                 ?         
Series III :             13              25          37           ?               
Series IV  :                         12               12           12                         
                                             0            0                         
Clearly, the pattern in series III is +12.
So, the missing term in series III = 37 + 12 = 49;
  missing term in series II = 82 + 49 = 131;
   missing term in series I = 173 + 131 = 304.
2. A)
Series Pattern                                 Given Series             
110                                                     110                  
110 + 15 (=1×3×5) = 125               125                  
125 + 105 (=3×5×7) = 230            230                  
230 + 315 (=5×7×9) = 545            545                  
545 + 693 (=7×9×11) = 1238        1238             
1238 + 1287 (=9×11×13) = 2525 2525             
3. B)
Series Pattern                                      Given Series         
420                                                          420  
420 – 7 (=1×7) = 413                           413  
413 – 21 (=3×7) = 392                         392  
392 – 35 (=5×7) = 357                         357  
357 – 49 (=7×7) = 308                         308
308 – 63 (=9×7) 245                         245
4. A)
5. C) 14 – 10 = 4
25 – 14 = 11 = 4 × 3 – 1
55 – 25 = 30 = 11 × 3 – 3
140 – 55 = 85 = 30 × 3 – 5
  X = 140 + 85 × 3 – 7 
         = 140 + 248 = 388
6. A)   7. B)   8. D)   9. B)   10. C)  
When x = 6, x > y and when x = −2, x < y
Thus, the relationship between x and y can't be established.
Hence, option E is correct.
12. E) Since both equations are of the form ax2 ± bx − c = 0, both equations have one positive and one negative root.
Hence, the relation between x and y can't be established.
When x = 21/5, x > y
When x = −3 and y = 3, x < y
For either value of x, x > y
When x = 8.5, x > y
When x = 2, x < y
Hence, the relationship between x and y cannot be established.
