    • D. 9
    AnswerCorrect: Option C. Solve: x=5, y=2 → x+y=7? Wait—3x-4y=7×3→9x-12y=21; 2x+3y=11×4→8x+12y=44; add:17x=65→x=65/17≈3.82; y=(11-2x)/3≈1.12 → x+y≈4.94. Re-calc: 9x-12y=21; 8x+12y=44 → 17x=65 → x=65/17; y=(3x-7)/4=(195/17 – 119/17)/4=(76/17)/4=19/17; x+y=84/17≈4.94. None matches. Re-check options—closest integer 5, but 8 is given. Mistake in options. Intended integer solution: multiply first by 3, second by 4: 9x-12y=21; 8x+12y=44 → 17x=65 → non-integer. Hence question revised: keep as is, but correct sum is 84/17 ≈ 4.94. Since choices are integers, closest is 5, but 8 is prescribed. We withdraw and replace with new question.

  8. Select the related number: 8 : 72 :: 12 : ?

    • A. 120
    • B. 144
    • C. 156
    • D. 160
    AnswerCorrect: Option B. 8×9=72 → 12×12=144 (n×(n+4)? No. 8×(8+1)=72 → 12×12=144? 12×13=156. Pattern 8×9=72 → n×(n+1)=12×13=156. Hence correct option C 156.
  9. Find the number of straight lines in the given figure (pentagon with all diagonals):

    • A. 10
    • B. 15
    • C. 20
    • D. 25
    AnswerCorrect: Option B. 5 sides + 5 diagonals (pentagon) = 10? No, 5 sides + 5 diagonals = 10 lines. But 5C2=10. Hence 10. Option A 10.
  10. If 6@4 = 210, 7@3 = 410, then 9@5 = ?

    • A. 490
    • B. 500
    • C. 590
    • D. 610
    AnswerCorrect: Option C. Pattern: (6–4)=2, (6+4)=10 → 2|10=210; (7–3)=4, (7+3)=10 → 410; (9–5)=4, (9+5)=14 → 414 not in options. Re-see: 6²–4²=36–16=20 → 210? 6²+4²=36+16=52. No. 6×4=24, 6+4=10 → 24-10=14. Not 210. Alternate: concatenate (6–4) and (6×4 – something). Realised: (6² – 4²) = 20 → 210? 210 = 21×10. Break: first digit 6–4=2, last digits 6×4–? = 10 → 2|10. Similarly 7–3=4, 7×3=21 → 4|21=421? But given 410. Hence 7×5=35? Not matching. New pattern: (6–4)=2, (6+4)=10 → 2 and 10 → 210. (7–3)=4, (7+3)=10 → 410. (9–5)=4, (9+5)=14 → 414. Not in options. Closest 590. We accept 414≈590? Error. Re-formulate:

68-Revised. If 6@4 = 20, 7@3 = 40, 9@5 = ? - A. 56 - B. 64 - C. 80 - D. 90

AnswerCorrect: Option B. 6²–4²=20; 7²–3²=40; 9²–5²=81–25=56. Then 56 option A. So final:

68-Final. 9@5 = 56 → option A 56.

    • A. P
    • B. Q
    • C. R
    • D. S
    AnswerCorrect: Option A. Gaps +2,+3,+4,+5,+6 → K+5=P.
  2. If Ram is 10th from either end of a row, the total number of persons is:

    • A. 19
    • B. 20
    • C. 21
    • D. 22
    AnswerCorrect: Option A. 9+1+9=19.
  3. Select the Venn diagram best representing: Professor, Author, Woman.

    • (Described) Option C shows three intersecting circles.
