In a certain language , if the word 'BASKET' os coded as 'UFLTBC', then how is the word 'SIMPLE' coded in that language?
1

Solution
BASKET → UFLTBC
Pattern:
Reverse +1
- Last letter T + 1 = U
- Second last E + 1 = F
- K + 1 = L
- S + 1 = T
- A + 1 = B
- First letter B + 1 = C
Applying to SIMPLE:
| Letter (Reverse Order) | Operation | Code |
|---|---|---|
| E (Last) | + 1 | F |
| L | + 1 | M |
| P | + 1 | Q |
| M | + 1 | N |
| I | + 1 | J |
| S (First) | + 1 | T |
Answer: FMQNJT
If Z = 52 and ACT = 48, then BAT will be equal to
1
2
3
4
Solution
We are given:
Z = 52
ACT = 48
Identify the rule
Each letter’s alphabetical position is multiplied by 2.
Value of a letter = (Alphabetical position) × 2
Verify with given examples
For Z: 26 × 2 = 52 ✔️
For ACT:
A = 1 × 2 = 2
C = 3 × 2 = 6
T = 20 × 2 = 40
Sum = 2 + 6 + 40 = 48 ✔️
Calculate BAT
B = 2 × 2 = 4
A = 1 × 2 = 2
T = 20 × 2 = 40
Sum = 4 + 2 + 40 = 46
✅ Final Answer: BAT = 46
Z = 52
ACT = 48

In a certain code language, the word "REASON" is encoded as TDDQSK. Using the same
rule, how is the word PRAYER coded?
1
2

Solution
Given: "REASON" is coded as "TDDQSK".
Write positions of letters (A=1, B=2, ..., Z=26):
R(18) → T(20): +2
E(5) → D(4): −1
A(1) → D(4): +3
S(19) → Q(17): −2
O(15) → S(19): +4
N(14) → K(11): −3
So the rule is:
+2, −1, +3, −2, +4, −3 (alternating + and −, with magnitude increasing).
Now apply same rule to "PRAYER":
P(16) +2 → R(18)
R(18) −1 → Q(17)
A(1) +3 → D(4)
Y(25) −2 → W(23)
E(5) +4 → I(9)
R(18) −3 → O(15)
Hence, "PRAYER" is coded as:
RQDWIO.
In a certain code language, "do re me" means "he is late"; "fa me la" means "she is early" and "so ti do" means "he leaves soon". Which word in the language means 'late"?
1
2
3
4
Solution
Given:
1) Compare "do re me" → "he is late" and "so ti do" → "he leaves soon".
Common word: "do"
Common meaning: "he"
⇒ So, "do" = "he"
2) Now in "do re me" → "he is late", remove "do" = "he"
Remaining: "re me" → "is late"
3) Compare "re me" → "is late" and "fa me la" → "she is early"
Common word: "me"
So, "me" appears in both and matches with: "late" or "early" — but can't be both.
But we already saw from above:
"me" appears in both 'late' and 'early' sentences → must be "is"
4) Now from "re me" → "is late", and "me" = "is", it implies:
"re" = "late"
Final Answer:
"re" means "late".
- "do re me" → "he is late"
- "fa me la" → "she is early"
- "so ti do" → "he leaves soon"
1) Compare "do re me" → "he is late" and "so ti do" → "he leaves soon".
Common word: "do"
Common meaning: "he"
⇒ So, "do" = "he"
2) Now in "do re me" → "he is late", remove "do" = "he"
Remaining: "re me" → "is late"
3) Compare "re me" → "is late" and "fa me la" → "she is early"
Common word: "me"
So, "me" appears in both and matches with: "late" or "early" — but can't be both.
But we already saw from above:
"me" appears in both 'late' and 'early' sentences → must be "is"
4) Now from "re me" → "is late", and "me" = "is", it implies:
"re" = "late"
Final Answer:
"re" means "late".

COUNSEL is to BITIRAK, so also GUIDANCE is to _______ ?

Solution
COUNSEL → BITIRAK
Pattern:
- C − 1 = B
- O − 6 = I
- U − 1 = T
- N − 5 = I
- S − 1 = R
- E − 4 = A
- L − 1 = K
Rule:
- Odd positions: −1
- Even positions: −6, −5, −4, −3...
Applying to GUIDANCE:
| Letter | Logic | Code |
|---|---|---|
| G | − 1 | F |
| U | − 6 | O |
| I | − 1 | H |
| D | − 5 | Y |
| A | − 1 | Z |
| N | − 4 | J |
| C | − 1 | B |
| E | − 3 | B |
Correct Answer: Option 2 (FOHYZJBB)
What are X and Y?
| S | 8 | W | 16 | A | 5 | C | X | A | 4 |
| 20 | J | 25 | T | 4 | K | 7 | L | Y | N |

Solution
Each letter corresponds to its alphabetical position:
A = 1, B = 2, C = 3, …, Z = 26.
Check pairs (top cell, bottom cell):
S → 19 and 20 → +1
8 → J (10) → +2
W (23) → 25 → +2
16 → T (20) → +4
A (1) → 4 → +3
5 → K (11) → +6
C (3) → 7 → +4
X (?) → L (12) → difference is 12 - ?
A (1) → Y (?)
4 → N (14)
We look for a consistent pattern.
Right-side pattern seems to be increasing by fixed differences.
The only option fitting the pair (X → L), meaning X must be 4 (since 12 - 4 = 8, matching nearby jumps), and Y must be 6 (since A=1 to Y=6 makes sense in pattern).
