Answer Key:
Q1. (A) cos63o = x
cos (90 – 27)o = x
sin27o = x
cos27o = 
tan27o = 
Q2. (B)
x – 2 = 6 + 2
= 2
(
+
)
= 2( +) 
Q3. (B) Speed of the man in still water/व्यक्ति की स्थिर जल में चाल = 10 km/hr./(किमी./घंटा)
Speed of the stream/धारा की चाल = 2 km/hr./(किमी./घंटा)
Required/अभीष्ट % = 
Q4. (C) When n is odd number, then/जब n एक विषम संख्या है, तो
Hence/यहाँ, 1739 + 2939 is divided by 17+29 = 46 i.e. 23 too
so remainder will be 0/अतः शेषफल 0 होगा ।
Q5. (B) tan θ = 
tan θ = 3
sec2 θ = 10
sin2 θ = 
Q6. (D) x2 + y2 + z2 = xy + yz + zx
2x2 + 2y2 + 2z2 = 2xy + 2yz + 2zx
x2 + y2 + z2 + x2 + y2 + z2 – 2xy – 2yz – 2zx = 0
(x – y)2 + (y – z)2 + (z – x)2 = 0
(x – y)2 = 0, (y – z)2 = 0, (z – x)2 = 0
x = y, y = z, z = x
x = y = z
Now/अब, 
= 
= 3/2
= = 3/2
Q7. (B)

Q8. (C) 
3a – 2 =

Q9. (C) 
Dividing both sides by cosq/ cosq से दोनों ओर भाग करने पर
5 + 12tanq = 13 secq
On squaring both sides, we get/दोनों ओर वर्ग करने पर, हम प्राप्त करते हैं
25 + 144 tan2q + 120 tanq = 169 sec2q
25 + 144 tan2q + 120 tanq = 169 (1 + tan2q )
25 tan2q – 120 tanq + 144 = 0
(5 tanq – 12)2 = 0
5 tanq – 12 = 0
tanq = 12/5
Q10. (A) AE = 5 cm/सेमी let/माना OF = x, CF = 12 cm/सेमी and/और OE = 17 – x
x2 + 122 = r2 ….. (I)
(17 – x)2 + 52 = r2 ….. (II)
From (I) and (II), we get/(I) और (II) से, हम प्राप्त करते हैं
x2 + 122 = (17 – x)2 + 52
34x = 170
x = 5
r2 = 52 + 122
= 25 + 144 = 169
r = 13
