(D) 4

Ans: C

In the first column, 12 x 6 = 72; 18 ÷ 3 = 3.
In the third column, 16 x 8 = 128; 32 ÷ 8 = 4.
In the second column, 14 x 8 = 112.
So, missing number = 24 ÷ 8 = 3.

In the first row, 5 x 1 = 5, 6 x 1 = 6, 5 + 6 = 11.
In the second row, 6 x 4 =24, 3 x 2 = 6, 24 + 6 = 30.
In the third row, 3 x 5 = 15, 4 x 3 = 12.
∴ Missing number = 15 + 12 = 27.

Question: 3

In each of the following questions, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.

(B) 16

(C) 17

(D) 19

Ans: B

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.

Question: 4

In each of the following questions, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.

(A) 3

(B) 4

(C) 5

(D) 6

Ans: C

In the first column, 29 – 8 = 7 x 3 = 21.
In the second column, 19 – 7 = 4 x 3 = 12.
Let the missing number in the third column be x.
Then, 31 – 6 = 5 x X or 5x = 25 or x = 5.

Question: 5

In each of the following questions, a matrix of certain characters is given. These characters follow a certain trend, row wise or column wise. Find out this trend and choose the missing character accordingly.

Clearly, (3rd column)2 + (2nd column) 2 = (1st column) 2
In the first row, 52 + 122 = 132.
In the second row, 82 + 152 = 172.
Let the missing number in the third row be x.
Then x2 + 242 = 252 or x2 + 576 = 625 or x2 = 49 or x = 7.
