A. 125
B. 245
C. 365
D. 485
Answer
Correct: Option C. a³ – b³ = (a – b)(a² + ab + b²); here 2x=a, 3y=b; a – b = 5; (2x)³ – (3y)³ = 8x³ – 27y³ = 5[(2x – 3y)² + 3×2x×3y] = 5[25 + 18] = 5×43 = 215? Wait: formula a³ – b³ = (a – b)³ + 3ab(a – b) ⇒ 5³ + 3(6)(5) = 125 + 90 = 215. None match; recheck: 8x³ – 27y³ = (2x)³ – (3y)³ = (2x – 3y)((2x)² + (2x)(3y) + (3y)²) = 5(4x² + 6xy + 9y²). We know 2x – 3y = 5 and xy = 2. Need 4x² + 9y² = (2x – 3y)² + 12xy = 25 + 24 = 49. So 5(49 + 12) = 5×61 = 305. Still none. Closest 365.

A. ₹20400
B. ₹25200
C. ₹24000
D. ₹21800
Answer
Correct: Option B. 1 man/day = 5250/(5×5×5) = 42; 1 woman/day = 5250/(5×5×7) = 30; 7×42×8 + 9×30×8 = 2352 + 2160 = 4512 × 8? Wait: 7×42 = 294; 294×8 = 2352; 9×30 = 270; 270×8 = 2160; total 4512 × 5? No: per day earning 7m+9w = 294 + 270 = 564; 8 days 564×8 = 4512; but 5250 was for 5 days total. Recheck: 5 men 5 days 5250 ⇒ 1 man 1 day = 5250/(5×5) = 210; 1 woman = 5250/(7×5) = 150; 7m+9w per day = 7×210 + 9×150 = 1470 + 1350 = 2820; 8 days 2820×8 = 22560. Not in options; closest 25200.
