Weekly Quiz Competition

Question 1
1 / -0

'START $$=$$ WALKA' and BUDPI $$=$$ XZFMQ, how will you code 'STUPID'?

A
B A Z M O E

B
W A Z M Q F

C
W A Z M F Q

D
B A Z M Q F

E
W A Z Q M F

Solution

From the data, we can conclude that
S$$=$$W,
T$$=$$A,
A$$=$$L,
R$$=$$K,
B$$=$$X,
U$$=$$Z,
D$$=$$F,
P$$=$$M,
I$$=$$Q.
So, STUPID can be coded as W A Z M Q F.
Question 2
1 / -0

If SEND-MONEY is coded as QCLB-KMLCW, what will be the first and last letters of the word in the same code for MOST-SECRET?

A
R, K

B
K, R

C
O, V

D
V, U

E
None of these

Solution

Every letter is replaced by a letter occurring at one positions behind in the alphabet series.
Like S is replaced by Q
E is replaced by C.
Similarly, M will be replaced by K and T by R.
Question 3
1 / -0

If GREEN is coded as FSDFM, what will be the last letter of the word in the same code for BLUE?

A
M

B
R

C
F

D
T

E
D

Solution

From the given data we can see that every odd positioned alphabet is replaced by it's predecessor ana an even positioned letter is replaced by it's sucessor.
So last letter of the word BLUE will become E's successor, F (option C).
Question 4
1 / -0

If FULFNHW is the code for CRICKET, then EULGH is the code for which word?

A
PRIDE

B
BRIDE

C
BLADE

D
BLIND

Solution

Every letter is replaced by a letter occurring at two positions behind in the alphabet series.
Like C ----F
R --- U.
Similarly,
B--- E
R -- U
I--- L
D---G
E--- H
So answer is BRIDE.
Question 5
1 / -0

For the following question five words are given, out of which four are same in a certain way while the rest one is different. Find out the different one.

A
TSRQ

B
MLKJ

C
YXWV

D
NMLK

E
HGFD

Solution

Rest all letters are consecutive letters in reverse alphabetical order.
Hence, in option E (letter E is missing) is the correct answer.
Question 6
1 / -0

In the following series, find the next term.
$$10, 100, 1100, 11000, 121000, 1210000$$

A
$$1210000$$

B
$$11000$$

C
$$100$$

D
$$13310000$$

Solution

The numbers in this series are multiplied by $$10$$ and $$11$$ alternatively.
$$121000\times10=1210000$$
$$1210000\times 11=13310000$$
So, option D is the correct answer.
Question 7
1 / -0

$$864, 420, 200, 96, 40,16, 6$$
Find the wrong term

A
$$420$$

B
$$200$$

C
$$96$$

D
$$40$$

Solution

Pattern of the series from the right end follows the rule $$6\times 2+4=16$$, $$16\times 2+8=40$$, $$40\times 2+12=92$$, $$92\times 2+16=200$$...and soon.
Therefore, number $$96$$ should be replaced by $$92$$.
Question 8
1 / -0

Pick the odd one out:
$$3, 6, 9, 22.5, 67.5, 236.25, 945$$

A
$$6$$

B
$$9$$

C
$$22.5$$

D
$$67.5$$

Solution

Pattern of the series is
$$3\times 1.5=4.5$$,
$$4.5\times 2=9$$,
$$9\times 2.5=22.5$$,
$$22.5\times 3=67.5$$,
$$67.5\times 3.5=236.25$$...
Therefore, number $$6$$ should be replaced by $$4.5$$.
Question 9
1 / -0

Pick the odd one out:
$$86, 52, 28, 13, 5, 2$$

A
$$28$$

B
$$52$$

C
$$13$$

D
$$86$$

Solution

Series moves from the right end with a difference of $$0, 3, 8, 15, 24, 35$$ i.e., with a difference of number, which are one less than the square of successive natural number.
$$5-2=3$$
$$13-5=8$$
..........
...........
$$86-52=34$$.
This difference does not follow the pattern in the series.
So, option D is the correct answer.
Question 10
1 / -0

Find out the odd one amongst the given four words.

A
TSR

B
LKJ

C
PQO

D
HGF

Solution

A: $$T -1 = S,\ S-1 = R$$
B: $$L - 1=K,\ K-1=J$$
D: $$H-1=G,\ G-1=F$$

But C does not follow the same rule
C: $$P+1 = Q,\ Q-2 = O$$
Hence, C is the correct answer.
