Verbal Reasoning
6.
 
  • A. 19
  • B. 17
  • C. 16
  • D. 15
Ans: C.
Sol.
In the first column, 112 - 12 = 121 - 1 = 120.
In the second column, 72 - 22 = 49 - 4 = 45.
In the third column, missing number = 52 - 32 = 25 - 9 = 16.
 
7.
 
  • A. 5
  • B. 9
  • C. 11
  • D. 14
Ans: A.
Sol.
In the second row, 2 × 9 + 3 × 17 = 18 + 51 = 69.
In the third row, 2 × 13+ 3 × 11 = 26 + 33 = 59.
Let the missing number in the first row be x.
Then, 2x + 3 × 13 = 49 or 2x = 10 or x = 5.
 
8.
 
  • A. 6
  • B. 7
  • C. 8
  • D. 9
Ans: A.
Sol.
Clearly, sum of numbers in each row is 17.
So, missing number = 17 – ( 4 + 7 ) = 6.
 
9.
 
  • A. 4
  • B. 8
  • C. 12
  • D. 14
Ans: B.
Sol.
Clearly, (1st row) x ( 2nd row) x (3rd row) = 4th row.
In the first column, 6 x 5 x 4 = 120.
In the second column, 6 x 7 x 3 = 126.
Let the missing number in the third column be x.
Then, 8 x 5 x X = 320.
40X =320 or X = 8.
 
 
10.
 
  • A. 4
  • B. 6
  • C. 36
  • D. 42
Ans: A.
Sol.
In the first column, 13 + 7 × 2 = 27.
In the second column, 54 + 45 × 2 = 144.
Let the missing number in the third column be x.
Then, x + 32 × 2 = 68 or x = 68 - 64 = 4.
