Total Questions: 25 | Marks: 50
Q1. If “CAT” is coded as “DBU,” how is “DOG” coded?
A) EPH
B) FQH
C) EPG
D) FPG
Answer: A) EPH
Explanation: Each letter in “CAT” is shifted forward by 1 (C→D, A→B, T→U). Apply the same rule to “DOG”: D→E, O→P, G→H. Thus, “DOG” becomes “EPH.”
Q2. Find the odd one out: 4, 9, 16, 25, 27
A) 4
B) 9
C) 16
D) 27
Answer: D) 27
Explanation: 4, 9, 16, and 25 are perfect squares (2², 3², 4², 5²), but 27 is not (5²=25, 6²=36). Hence, 27 is the odd one out.

Q4. If 20% of a number is 15, what is 60% of that number?
A) 45

D) 75
Answer: A) 45
Explanation: Let the number be x. Given 20% of x = 15, so 0.2x = 15 → x = 15 / 0.2 = 75. Now, 60% of 75 = 0.6 × 75 = 45.

A) 7/6

Answer: A) 7/6
Explanation: Find a common denominator (6): (2/3) = 4/6, (5/6) = 5/6, (1/2) = 3/6. Then, 4/6 + 5/6 – 3/6 = (4 + 5 – 3) / 6 = 6/6 + 1/6 = 7/6.
