Difference between terms: +3, +5, +7, +9 → next is +11. So, 18 + 9 = 27.

T→W (+3), O→S (+4), D→G (+3), A→D (+3), Y→B (+3). Apply same logic: N→P, I→J, G→I, H→F, T→V → Code is PJIFV.

Each letter is skipping one in the alphabet: C (+2) E (+2) G (+2) I (+2) → next is K.

Each number is multiplied by 2: 9×2 = 18, 18×2 = 36, 36×2 = 72, 72×2 = 144. So the missing number is 72.

Explanation: The correct meaningful word formed from RTAF is RAFT, which is a small flat boat. All other options are meaningless or not actual English words.

Answer: D. 35 Explanation: This is a series of n² - 1: 1² - 1 = 0 2² - 1 = 3 3² - 1 = 8 4² - 1 = 15 5² - 1 = 24 6² - 1 = 35 → Answer is 35

Numbers increase by 2: 2, 4, 6, 8 → next is 10. Letters: A, C, E, G → skip 1 each time (A + 2 = C, +2 = E...) → next is I.

From the statements, we cannot deduce that some pens are chairs or that all books are pens. Both conclusions go beyond the given statements.

26 Explanation: Pattern is: n² + 1 → 2² + 1 = 4 + 1 = 5 3² + 1 = 9 + 1 = 10 4² + 1 = 16 + 1 = 17 So, 5² + 1 = 25 + 1 = 26.

All numbers except 90 are perfect squares: 6² = 36, 7² = 49, 8² = 64, 9² = 81. 90 is not a perfect square, hence the odd one.

Cow, buffalo, and goat are domesticated animals, while the tiger is a wild animal. Thus, tiger is the one that doesn't fit the group.

All numbers except 90 are perfect squares: 6² = 36, 7² = 49, 8² = 64, 9² = 81. 90 is not a perfect square, hence the odd one.

This is a cube analogy. 3³ = 27, so 5³ = 125. Hence, the answer is 125.

(5 + 3) = 8 → 8×3 = 24 (6+4) = 10 × 4 = 40 (7+5) = 12 × 5 = 60 → Answer is 60 Correction: Answer: A. 60

These numbers are squares of consecutive integers: 2²=4, 3²=9, 4²=16, 5²=25, so the missing number is 6² = 36, followed by 7² = 49.

Apple, banana, and mango are fruits, while carrot is a root vegetable. It is the only item not belonging to the fruit category, making it the odd one out

Each letter is incremented by 1: R → S, A → B, M → N. Similarly, K → L, I → J, T → U, E → F. Thus, KITE becomes LJUF.

Using the provided codes: N=9, E=1, P=3, A=5, L=7. Arranging for PANEL → P(3), A(5), N(9), E(1), L(7) gives 91357 as the correct code.

Raj's father's only sister is his aunt. The girl is the daughter of his aunt, making her Raj’s cousin. Hence, the correct relation is cousin.

Rearranging the word TRUST to USRTT involves placing vowels in front alphabetically and consonants after them alphabetically. For FAITH, vowels (A, I) come first alphabetically, then consonants (F, H, T) follow alphabetically → AIFHT.

In this series, the first letters are moving alphabetically forward: A, B, C, D. The second letters are moving backward from Z: Z, Y, X, W. So, the correct pair following CX is DW.

U(21) + P(16) = 37. This is a simple summation of alphabetical positions of letters in the word “UP”. The key is identifying positional value of letters

Rotating the clock doesn’t change the time; it only changes the clock’s orientation

Circle appears three times, Square and Triangle once each. Square is the first to break the Circle pattern.

Each number is doubled: 3×2=6, 6×2=12, 12×2=24, 24×2=48.

Square, Circle, and Triangle are basic shapes; Hexagon has more sides, making it different.

The series represents perfect squares: 1², 2², 3², 4². The next is 5² = 25.

A 90° clockwise rotation changes a square’s orientation, making its sides diagonal relative to the original position.
