100+ SSC Inserting the Missing Character Questions - 1

Question: 1

Find the missing character in each of the following questions.

(A) 1

(B) 25

(C) 125

(D) 216

Ans: D

Clearly, (5 – 4)3 = 1; (7 - 3)3 = 64; (11 - 8)3 = 27.
So, missing number = (8 - 2)3 = 63 = 216.

Question: 2

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) 40

(B) 48

(C) 56

(D) 64

Ans: B

The sequence in first column is ×5. Thus, 1 x 5 = 5, 5 x 5 = 25, 25 x 5 = 125.
The sequence in third column is ×2. Thus, 7 x 2 = 14, 14 x 2 = 28, 28 x 2 = 56.
The sequence in second column is ×4.
Missing number = 12 x 4 = 48.

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.

(A) 15

(B) 16

(C) 17

(D) 18

Ans: D

In the first row, 3 x 4 + 3 = 15.
In the second row, 7 x 5 + 3 = 38.
In the third row, missing number = 3 x 5 + 3 = 18.

Question: 4

Find the missing character in each of the following questions.

(A) 1

(B) 2

(C) 3

(D) 4

Ans: A

The two ends of each line segment contain a number and its square.
So, missing number = 12 = 1.

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.

(A) P

(B) R

(C) S

(D) V

Ans: B

Putting A = 1, B = 2, Z = 26, we get the given matrix as
Clearly, 1st column + 2nd column = 3rd column.
Now, 5 + 13 = 18.
So, the missing letter is the 18th letter of the alphabet, which is R.
