- 2. In a certain code language, GRAPE is written as 27354 and FOUR is written as 1687 . How is GROUP written is that code?
Options- A. 27384
- B. 27684
- C. 27685
- D. 27658 Discuss
Correct Answer: 27685
Explanation:
GRAPE = 2 7 3 5 4
FOUR = 1 6 8 7
So, G = 2, R = 7, A = 3, P = 5, E = 4,
F = 1, O = 6, U = 8,
R = 7
GROUP = 2 7 6 8 5
- 3. If 1 + 4 = 9, 2 + 8 = 18, 3 + 6 = 15 then 7 + 8 =?
Options- A. 41
- B. 23
- C. 30
- D. 32 Discuss
Correct Answer: 23
Explanation:
The given logic is as follows,
Sum of the digits + second digit = Answer.
i.e., 1 +4 = 5 + 4 = 9
2 + 8 = 10 + 8 = 18
Similarly, 7 + 8 = 15 + 8 = 23.

- 6. If 0, 1, 2, 3,......, 9 is written as a, b, c, d,.....j, then find dc x f - (bf - d) x d.
Options- A. abc
- B. bcf
- C. abb
- D. bcc Discuss
Correct Answer: bcc
Explanation:
dc x f - (bf - d) x d
the values of alphabets...........
= 3.2 x 5 - (1.5 - 3) x 3
= 6 x 5 - (5 - 3) x 3
= 30 - 6 = 24 = 2 + 4 = 6 = bcc
- 7. In a certain code PATHOLOGIST is written as PIUBQKSRHFN. How is CONTROVERSY written in that code?
Options- A. SUOPDNXRQDU
- B. SUOPDNZTSFW
- C. QSMNBPXRQDU
- D. QSMNBPZTSFW Discuss
Correct Answer: SUOPDNXRQDU
Explanation:
Five letters of the word PATHOLOGIST are reversed first and then coded as one place forward. Similarly, the last five letters of the word are reversed then coded as one place backward. Middle letter is coded as one place backward.
Hence, CONTROVERSY will be written as SUOPDNXRQDU.
- 8. The following small letters are coded by capital letters in a certain way :
s u m l a d
R A P M S O
Now, which small letters can be decoded from the letters given below :
M A P S R O
Options- A. lumdas
- B. lumsda
- C. lumasd
- D. lumsad Discuss
Correct Answer: lumasd
Explanation:
According to given question,
R = s
A = u
P = m
M = l
S = a
O = d
Replace the each capital from given relationship for M A P S R O, We will get
M ? l
A ? u
P ? m
S ? a
R ? s
O ? d
