Question 1: Study the given pattern carefully and select the number that can replace the question mark (?) in it. a) 29

b) 27

c) 30

d) 24

Solution:

Along the rows, the second number is obtained by dividing the first number by 6 or dividing the third number by 4 as shown below

$\frac{150}{6}=25$   or    $\frac{100}{4}=25$

$\frac{132}{6}=22$   or    $\frac{88}{4}=22$

Similarly, the required number = $\frac{162}{6}=27$

Hence, the correct answer is Option B

Instructions

In the following questions, select the missing number from the given responses.

Question 2: a) 64

b) 69

c) 65

d) 68

Solution:

13 $\times$ 2 + 4 = 30

Question 3: Select the missing number from the given responses a) 17

b) 1

c) 19

d) 7

Solution:

From the table along the rows,

1 + 5 = 6

6 + 7 = 13

Third number is equal to first number and second number along the rows.

Similarly along the third row,

The missing number = 8 + 9 = 17

Hence, the correct answer is Option A

Question 4: Select the missing number from the given responses. a) -6

b) 1

c) -1

d) 14

Solution:

From the table along the rows,

7 – 4 = 3

1 – 5 = -4

Difference between the first number and second number along the rows is equal to the third number.

Let the missing number = a

Similarly along the second row,

4 – 10 = a

$\Rightarrow$  a = -6

$\therefore\$The missing number = -6

Hence, the correct answer is Option A

Question 5: Select the missing number from the given responses a) 2

b) 10

c) 7

7 – 9 = -2

Difference of first number and second number is equal to third number along the columns.

Let the missing number = a

Similarly along the second column,

4 – a = -6

$\Rightarrow$  a = 10

$\therefore\$The missing number = 10

Hence, the correct answer is Option B

Question 6: Select the missing number from the given responses a) 10

b) 8

c) -6

d) 6

Solution:

Along the second column and third column,

6 – 3 = 3

6 – 1 = 5

Difference of first two numbers in a column is equal to the third number in the column.

Let the missing number = a

Similarly from the first column,

2 – 8 = a

$\Rightarrow$  a = -6

$\therefore\$The missing number = -6

Hence, the correct answer is Option C

Question 7: Select the missing number from the given responses a) 21

b) 14

c) 6

d) 3

Solution:

From the table along the columns,

7 + 2 = 9

Sum of first number and second number is equal to third number along the columns.

Let the missing number = a

Similarly along the third column,

4 + 10 = a

$\Rightarrow$  a = 14

$\therefore\$The missing number = 14

Hence, the correct answer is Option B

Question 8: Select the missing number from the given responses. a) 1

b) 9

c) -1

d) -9

Solution:

From the table along the columns,

8 + 9 = 17

2 + 8 = 10

Sum of the top two numbers is equal to the bottom number in a column.

Let the required number = a

Similarly, 10 + a = 19

$\Rightarrow$  a = 9

$\therefore\$The required number = 9

Hence, the correct answer is Option B

From the second column, the required number = 7 + 8 = 15

Hence, the correct answer is Option C

Question 10: Select the missing number from the given responses a) 6

b) 14

c) 1

d) 17

Solution:

From the table,

1 + 7 = 8

4 + 5 = 9

Along the rows, sum of first number and second number is equal to the third number.

Similarly, the required number = 4 + 10 = 14

Hence, the correct answer is Option B

Question 11: Select the missing number from the given responses a) 3

b) 9

c) -3

d) 11

Solution:

Along the columns,

$1+2=3$

$2+10=12$

Sum of the first and second number is equal to the third number along the columns.

Similarly, the required number $=4+7=11$

Hence, the correct answer is Option D

Question 12: Study the given pattern carefully and select the number that can replace the question mark (?) in it? a) 14

b) 24

c) 30

d) 28

Solution:

$\frac{299 + 100}{21} = \frac{399}{21}$ = 19
$\frac{296 + 100}{18} = \frac{396}{18}$ = 22
Similarly,
$\frac{348 + 100}{32} = \frac{448}{32}$ = 14
$\therefore$ The correct answer is option A.

b) 3

c) 5

d) 6

Solution:

$\frac{29 + 3}{8} = \frac{32}{8} = 4$
$\frac{71 + 6}{11} = \frac{77}{11} = 7$
$\frac{67 + 3}{14} = \frac{70}{14} = 5$
$\therefore$ The correct answer is option C.

Question 14: Study the given pattern carefully and select the number that can replace the question mark (?) in it. a) 27

b) 28

c) 29

d) 25

Solution:

The logic here is

$\left(10-3\right)\times2=14$

$\left(49-15\right)\times2=68$

Along the rows, twice the difference of first number and second number is equal to third number.

Similarly from the third row, the required number = $\left(33-19\right)\times2=28$

Hence, the correct answer is Option B

Question 15: Study the given pattern carefully and select the number that can replace the question mark (?) in it. a) 217

b) 203

c) 199

d) 195

Solution:

The logic here is

Along first row

11 + 2 = 13

13 + 4 = 17

Along second row

33 + 2 = 35

35 + 4 = 39

Along the rows, second number is the sum of first number and 2, third number is the sum of second number and 4.

Similarly,

Along the third row

189 + 2 = 191

191 + 4 = 195

$\therefore\$The required number = 195

Hence, the correct answer is Option D
