ACE : I : : GHI : ?

  1. U

  2. V

  3. W

  4. Y

  5. X
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Adding the place values of A, C and E, we get 1 + 3 + 5 = 9, the place value of I. So, it is represented by I. Similarly, G = 7, H = 8 and I = 9. 7 + 8 + 9 = 24, which is represented by X. It is the correct answer.

D : B : : X : ?

  1. K

  2. M

  3. N

  4. L

  5. O
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D is represented by B. The place value of D is 4, which is halved and the result is 2, the place value of B. Similarly, X = 24. Dividing it by 2, we get 12. It is the place value of L. So, this is the correct answer.

HB : P : : CF : ?

  1. P

  2. Q

  3. R

  4. S

  5. T
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The place values of H and B are 8 and 2 are multiplied to get 16, which is the place value of P. Similarly, C and F (place values 3 and 6), when multiplied, give 18. 18 is the place value of R. So, this is the correct answer.

Multiple choice

Directions: In the following question there is some relationship between the two terms to the left of : : and the same relationship is between the two terms to its right. One term either to the right of : : or to the left of it is missing. Find the missing term.

corden : zrogbq : : ? : pxivro

  1. mulmul

  2. sulsul

  3. munmun

  4. srspql
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The pattern is an alternating letter cipher with shifts of -3 and +3. For CORDEN to ZROGBQ: C→Z (-3), O→R (+3), R→O (-3), D→G (+3), E→B (-3), N→Q (+3). Applying the reverse pattern to PXIVRO: P→S (+3), X→U (-3), I→L (+3), V→S (-3), R→U (+3), O→L (-3), giving SULSUL.

Directions: In the following question there is some relationship between the two terms to the left of : : and the same relationship is between the two terms to its right. One term either to the right of : : or to the left of it is missing. Find the missing term.

? : QEHMDF : : WIDELY : HVCDXK

  1. DEMAND

  2. FRANCE

  3. FRINGE

  4. STRING
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The encoding shifts each letter of FRINGE to get QEHMDF: F→Q (+11), R→E (-13), I→H (+8), N→M (-10), G→D (-2), E→F (+1). While WIDELY→HVCDXK follows a similar shifting pattern, the exact shifts differ. FRINGE is the only option that produces the given encoded form.

BUCKET : ACTVBDJLDFSU : : BONUS : ?

  1. ACMNMOTVRT

  2. SUNOB

  3. ACNPMOTVRT

  4. ACMNMOTURT
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

ACTVBDJLDFSU is BUCKET with letters rearranged: B-U-C-K-E-T in alphabetical order becomes B-C-E-K-T-U, then positioned as A-B-C-(D)-E-F-(H)-J-(K)-L-(T)-(U) at positions 1,2,3,4,5,6,8,10,11,12,15,16,17,18,19. The pattern is spelling BUCKET with letters placed at increasing positions with gaps. For BONUS (alphabetical: B-N-O-S-U), the gaps follow the same pattern, giving ACNPMOTVRT.

Multiple choice

Directions: The following question consists of a pair of letter groups that have a certain relationship to each other, followed by four other pairs of letter groups given as alternatives. Select the pair in which the letter groups are similarly related as in the given pair.

MN : OP

  1. AD : GH

  2. AB : PQ

  3. QR : ST

  4. RS : TV
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Both pairs show consecutive letters that are 2 positions apart. MN→OP: M(13) and N(14) are consecutive, O(15) and P(16) are the next two. Similarly, QR→ST: Q(17) and R(18) are consecutive, S(19) and T(20) follow. The relationship is two consecutive letters followed by the next two consecutive letters.

Directions: In the following question there is some relationship between the two terms to the left of : : and the same relationship is between the two terms to its right. One term either to the right of : : or to the left of it is missing. Find the missing term.

C : 16 : : F : ?

  1. 30

  2. 40

  3. 49

  4. 50
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The relationship is: letter position squared. C is the 3rd letter, and 3² = 9, but wait that doesn't match 16. Let me reconsider. If C=3 and we need 16, the pattern might be (position+1)²: (3+1)² = 16. For F (6th letter): (6+1)² = 49. This fits perfectly.
