Question

Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

ACE EIM IOU MUC ?

• A. QSA
• B. UHG
• C. QAK
• D. CGD

Answer 1

Answer:

C. QAK

Given series:

• ACE

• EIM

• IOU

• MUC

• ?

Observe each position separately.

1st letters:

A → E → I → M

Each moves forward by 4 letters.

So next letter:
M + 4 = Q

2nd letters:

C → I → O → U

Each moves forward by 6 letters.

So next:
U + 6 = A (after Z, continue from A)

3rd letters:

E → M → U → C

Each moves forward by 8 letters.

So next:
C + 8 = K

Hence the required letter-cluster is:

QAK
