  carefully to understand how the coding or
  decoding is being done.
• Look for Shifts: Observe if there's a consistent
  shift in letters or numbers (e.g., A->C, B->D
  means a shift of +2).
• Understand Rules: Determine if the encoding
  is based on positional values (A=1, B=2),
  opposite letters (A=Z, B=Y), or some other
  rule.

1. "Pointing to a photograph, a woman says, 'He is the only son of my mother's
father's only daughter-in-law's only brother's wife.' How is the woman related to
the man in the photograph?"
      Explanation:
          1. Mother's father = Grandfather
          2. Grandfather's only daughter-in-law = Woman's mother
          3. Mother's only brother = Woman's uncle
          4. Uncle's wife = Aunt by marriage
          5. Aunt's only son = Cousin
       Therefore, the woman is related to the man in the photograph as his COUSIN.
      Answer: C. COUSIN
2. "A man said to a woman, 'Your mother’s brother’s only daughter is my wife’s
sister-in-law.' How is the woman related to the man?"
      Explanation:
          1. Mother's brother's only daughter = Woman's cousin
          2. Man's wife's sister-in-law = Man's wife's brother's wife = Woman's cousin
       Therefore, the woman is related to the man as his SISTER-IN-LAW.

3. "In a family, the father's age is three times the age of his son. Four years ago,
the father's age was four times the age of his son. Find the present ages of the
father and the son."
      Explanation:
          1. Let the son's age be xx years.
          2. Father's age is 3x3x years.
          3. Four years ago:
                  Son's age: x−4x - 4
                  Father's age: 3x−43x - 4
          4. Equation: 3x−4=4(x−4)3x - 4 = 4(x - 4)
3x−4=4x−163x - 4 = 4x - 16
16−4=4x−3x16 - 4 = 4x - 3x
x=12x = 12
Therefore, the son's present age is 12 years, and the father's present age is 3×12=363 \times 12 =
36 years.
      Answer: B. SON 12 FATHER 36
4. "The present ages of three siblings, Alex, Bella, and Charlie, are in the ratio
4:5:6, respectively. If the sum of their ages is 45 years, what will be the ratio of
their ages after 5 years?"
      Explanation:
          1. Let the present ages be 4x,5x,6x4x, 5x, 6x.
          2. Sum of ages: 4x+5x+6x=454x + 5x + 6x = 45
15x=4515x = 45
x=3x = 3
   3. Present ages:
         o Alex: 4×3=124 \times 3 = 12 years
         o Bella: 5×3=155 \times 3 = 15 years
         o Charlie: 6×3=186 \times 3 = 18 years
   4. Ages after 5 years:
         o Alex: 12+5=1712 + 5 = 17 years
         o Bella: 15+5=2015 + 5 = 20 years
         o Charlie: 18+5=2318 + 5 = 23 years
   5. Ratio of ages after 5 years: 17:20:2317:20:23
      Answer: B. 17:20:23
