1739 + 2939 को 23 से भाग देने पर शेषफल है ?
(A) 17
(B) 1
(C) 0
(D) 29

Q5. If 0 < θ < 900, tan θ = then find the value of .

यदि 0 θ < 900, tan θ = हो तो का मान ज्ञात कीजिये ।
(A) 109
(B) 109/10
(C) 190/10
(D) 109/190

Q6. If x2 + y2 + z2 = xy + yz + zx, (x 0) then the value of

यदि x2 + y2 + z2 = xy + yz + zx, (x 0) then the value of
(A) 0
(B) 1
(C) 1/2

(D) 5/12

Q10. AB and CD are two parallel chords of a circle lying on the opposite side of the centre and the distance between them is 17 cm. the length of AB and CD are 10 cm and 24 cm respectively. The radius of the circle?

AB और CD एक वृत्त की दो समांतर जीवा है जो केंद्र के विपरीत और है और उनके बीच के दूरी 17 सेमी है AB और CD की लम्बाई क्रमश: 10 सेमी और 24 सेमी है वृत्त की त्रिज्या है? 
(A) 13
(B) 15
(C) 18
(D) 9

Answer Key:
Q1. (A) cos63o = x
cos (90 – 27)o = x
sin27o = x
cos27o =
tan27o =

Q2. (B) 
x – 2 = 6 + 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 

Q7. (B) =
=
= = 1

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 sec2
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
