(A) 0
(B) 1
(C) 2
(D)

Q1. (A)

Q2. (B) x = k3 – 3k2, y = 1 – 3k
k3 – 3k2 = 1 – 3k
k3 – 3k2 + 3k -1 = 0
k3 – 1 – 3k (k – 1) = 0
(k – 1)3 = 0
k = 1

Q3. (B) SP of article/वस्तु का विक्रय मूल्य = = 475
125 CP/क्रय मूल्य = Rs.47500
CP/क्रय मूल्य = Rs.380

Q4. (A) A ……… 12              5
60
B ……… 15              4
According to the question/प्रश्नानुसार,
5(5 + 4) + 5x = 60
5x = 60 – 45
5x = 15
x = 3

Q5. (B) cot 9o cot 27o.cot 63o.cot 81o
= cot 9o cot 27o.cot (90o – 27o) .cot (90o – 9o)
= cot 9o cot 27o.tan 27o. tan9o = 1

Q6. (A) Let their ages be 4x and 7x/माना उनकी आयु क्रमशः 4x और 7x हैं ।
7x – 4x = 30
3x = 30
x = 10 years/वर्ष
Sum of their ages/उनकी आयुओं का योग = 4x + 7x
= 11x = 11×10 = 110 years/वर्ष

Q7. (D) tan2 θ + 3 = 3sec θ
sec2 θ – 1 + 3 = 3sec θ
sec2 θ – 3 sec θ + 2 = 0
sec2 θ – 2 sec θ – sec θ + 2 = 0
(sec θ – 2) (sec θ – 1) = 0
sec θ – 2 =0
sec θ = 2
sec θ = sec 60o
sec θ – 1 = 0
sec θ = 1
sec θ = sec 0o
θ = 60o, 0o

Q8. (D)
a = 24
Area of square/वर्ग का क्षेत्रफल = 24 × 24 = 576
Volume of pyramid/पिरामिड का आयतन =
= 1152 m3/मी.3

Q9. (C) Relative speed/सापेक्ष चाल = 84 + 6 = 90 km/hr. /(किमी./घंटा)
= m/s. /(मी./से.)
Length of train/ट्रेन की लम्बाई = 25 × 4 = 100 m. /मी.

Q10. (C) sin265o + sin225o + cos235o + cos255o
= sin265o + sin2 (90o – 65o) + cos2 (90o – 55o) + cos255o
= sin265o + cos265o + sin255o + cos255o
= 1 + 1
= 2
