(D) Can't be determined/ज्ञात नहीं किया जा सकता

ANSWER KEY:
Q1. (C) 2cos2A + 3cosA = 2, then 4sin4A+ 9sin2A = ?
3cosA = 2(1 – cos2A) 
3cos A = 2sin2A (squaring both sides/ दोनो तरफ वर्ग करने पर)
9cos2A = 4 sin4A
9(1 - sin2A) = 4 sin4A 
then/तो,
4sin4A+ 9sin2A = 9

Q2. (D) sin A = 3/4
(tan2A – sec2A) – 3sin2A+ 2cos2A. 
= – 1 × 3 × (3/4)2 + 2 – 2(3/4)2= – 29/16

Q3. (C),
a = 7 + 4√3 a2 = 97 + 56√3
b = 7 - 4√3 b2 = 97 - 56√3
Then/तो, a2 + b2 + ab = 97 + 56√3 + 97 – 56√3 + 1 = 195

Q4. (C) 1089 cm2/सेमी2

Q5. (C) Let profit = Loss = x
माना लाभ = हानि = x 
Then/तो, 
1800 – x = x – 1400
x = 200
C.P./क्रय मूल्य = 1400 + 200 = 1600 
S.P./विक्रय मूल्य = = Rs.2160

Q6. (A)
x + y = 16
x – y = 8
x = 12
y = 4
Required ratio/अभीष्ट अनुपात = 12: 4 = 3: 1

Q7. (D)
A: B =

Q8. (C) Volume/आयतन = = 144

Q9. (D)

Q10. (B) (10x + y) + (10y + x) = 11(x + y)
Then/तो (x + y) = 11
For perfect square/पूर्ण वर्ग के लिए
