Q:

# In the following question, 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. 1 7 9 2 14 ? 3 105 117

 A) 26 B) 20 C) 16 D) 12

Answer:   D) 12

Explanation:

In the first column, 2 x 1 + 1 = 3.
In the second column, 14 x 7 + 7 = 105.
Let the missing number in the third column be y.
Then, y x 9 + 9 = 117 or  9y = 108  or  y = 12.

Q:

Which number replaces 'x' in the below figure ?

 A) 2 B) 9 C) 11 D) 12

Answer & Explanation Answer: B) 9

Explanation:

Here in 2nd column if you add the individual digits

we get  3 + 7 + 0 =10 , 2 + 2 + 4 = 8 , 7 + 3 + 0 = 10

7   10   3  $\Rightarrow$ 7+3 =10

6   8     2  $\Rightarrow$ 6+2 =8

x   10   1  $\Rightarrow$ x+1 =10

Here we can observe that by adding 1st and 3rd column elements we get 2nd column elements

$\Rightarrow$ x = 9

Q:

What value replaces " ? " in the below figure ?

 A) 4 B) 3 C) 2 D) 1

Answer & Explanation Answer: D) 1

Explanation:

Here it follows

$\inline \fn_jvn \small \frac{42}{6}-\frac{15}{3}=2$ and  $\inline \fn_jvn \small \frac{38}{19}-\frac{20}{10}=0$

In the same way  $\inline \fn_jvn \small \frac{36}{9}-\frac{9}{3}=1$

Q:

What replaces "?" in the below figure?

 A) 35 B) 34 C) 26 D) 24

Answer & Explanation Answer: C) 26

Explanation:

Here $\inline \frac{14\times 15}{21}$ = 10 and $\inline \frac{32\times 14}{28}$ = 16

In the same way $\inline \frac{24\times 26}{24}$ = 26.

Q:

$\inline \fn_cm \begin{matrix} CK & 16 & 9 & JR\\ OS & 24 & 19 & TX\\ KM& ?& ? & PV \end{matrix}$

 A) 14,21 B) 21,14 C) 56,84 D) 84,56

Answer & Explanation Answer: B) 21,14

Explanation:

Putting A=1, B=2, C=3,..., M=13,....,X=24,Y=25, Z=26, we have :

$\inline \fn_cm JR=\frac{J+R}{2}+2=\frac{10+18}{2}+2=16$

$\inline \fn_cm CK=\frac{C+K}{2}+2=\frac{3+11}{2}+2=9$

$\inline \fn_cm TX=\frac{T+X}{2}+2=\frac{20+24}{2}+2=24$

$\inline \fn_cm OS=\frac{O+s}{2}+2=\frac{15+19}{2}+2=19$

So, the missing numbers are :

$\inline \fn_cm (i)\; PV=\frac{P+V}{2}+2=\frac{16+22}{2}+2=21$

$\inline \fn_cm (ii)\; KM=\frac{K+M}{2}+2=\frac{11+13}{2}+2=14$

Hence, the answer is (b).

Q:

In the following question, 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 G N D J R G N ?

 A) U B) V C) W D) X

Answer & Explanation Answer: C) W

Explanation:

The letters in the first row follow the sequence +5, +7.

The letters in the second row follow the sequence +6, +8.
In the third row, the first letter G moves 7 steps forward to give the second letter N.
Clearly, the missing letter will be 9 steps ahead of N i.e. W.
