SSC CPO & Constable Mock Test (GI Reas) 6 Free Online Test 2026

Analyzing the Pattern:

1. C → F: Move 3 letters forward in the alphabet (C → D → E → F).
2. B → E: Move 3 letters forward in the alphabet (B → C → D → E).
3. D → G: Move 3 letters forward in the alphabet (D → E → F → G).

Applying the Same Pattern to "SRT":

1. S → V: Move 3 letters forward (S → T → U → V).
2. R → U: Move 3 letters forward (R → S → T → U).
3. T → W: Move 3 letters forward (T → U → V → W).

Thus, SRT becomes VUW when applying the same pattern.

Correct Answer:

C: VUW

Step 1: Understanding the Letter Interchange

The problem states that the first letter of the English alphabet is interchanged with the 14th letter, the second letter with the 15th letter, and so on. This means:

• A ↔ N
• B ↔ O
• C ↔ P
• D ↔ Q
• E ↔ R
• F ↔ S
• G ↔ T
• H ↔ U
• I ↔ V
• J ↔ W
• K ↔ X
• L ↔ Y
• M ↔ Z

Step 2: Determine the 17th Letter from the Right

In the English alphabet:

• The 17th letter from the right is the 10th letter from the left, which is J.

After the interchange, J is swapped with W.

Step 3: Find the 9th Letter to the Right of W

Starting from W:

• 1st: X
• 2nd: Y
• 3rd: Z
• 4th: A (after the full cycle, back to A)
• 5th: B
• 6th: C
• 7th: D
• 8th: E
• 9th: F

Conclusion:

The letter that is 9th to the right of the 17th letter from the right is F.

Correct Answer:

A: F

In fig. (A), 6² = 36, 8² = 64, 5² = 25, 7 2 = 49. And, 6+8+5+7=26.
In fig. (B), 3² = 9, 5² = 25, 4² = 16, 9 2 = 81. And, 3+5+4+9=21.
In fig. (C), 5² = 25, 12² = 144, 6² = 36, 8² = 64.
So, missing number = 5+12+6+8=31.

4 alphabets would not change their position when arranged alphabetically

(20)² ÷ 25 + 5 x 3
= 400 ÷ 25 + 5 x 3 (use BODMAS Rule)
= 16 + 15 = 31

(7 P 3) Y6X5
= (7 × 3) - 6 + 5
= 21 - 6 + 5
= 26 - 6
= 20
