Q.10. If (3.7)x = (0 .037)y = 10000 then what is the value of ?
यदि (3.7)x = (0 .037)y = 10000 हो, तो का मान क्या है?
(A) 2 
(B) – 2 
(C)
(D)

Answer Key:

Q1. (D) f (x) = x5 – qx2 + 12x – 14
                  f (3) = (3)5 – 9(3)2 + 12(3) – 14
                          = 243 – 9 × 9 + 36 – 14
                          = 184

Q2. (C) l

Q3. (D) The amount Q should have received/वह राशि जो Q को प्राप्त होनी चाहिए = 5x
But the amount he actually get/लेकिन वह राशि जो उसे वास्तविकता में मिली
=
Difference/अंतर = 5x – =
= 10
x = 50 
Total amount/कुल राशि = 8x = Rs.400

Q4. (B)
Let the wire be wounded n times around the cylinder, then 
माना तार की बेलन के चारों ओर n बार मोड़ा जाता है, तो
= height of the cylinder/बेलन की ऊँचाई
Length of the wire/तार की लम्बाई = = 2000 cm./सेमी. = 20 m. /मी.

Q5. (B) X Y
3 years ago/3 वर्ष पहले y + 3 y
Present age/वर्तमान आयु 2y y + 3
The difference/अन्तर = 2y – (y + 3) = 3
y = 6
Present age of X/X की वर्तमान आयु = 6 × 2 = 12 years/वर्ष

Q6. (A) x4 + 4y4 = x4 + 4y4 + 4x2y2 – 4x2y2
                               = (x + 2y) 2 – (2xy) 2
                               = (x2 + 2y2 – 2xy) (x2 + 2y2 + 2xy)
                  That is divisible by (x2 + 2y2 + 2xy)/जोकि (x2 + 2y2 + 2xy) से विभाज्य है ।

Q7. (B) [(1 – sin2q) sec2q + tan2q] (cos2q + 1)
                    = (sec2q - tan2q + tan2q) (cos2q + 1)
                    
sec2q > 1, 0 < q < 900
                                
= 1 + sec2
q > 1 + 1 > 2

Q8. (A) Let the roots of the equation lx2 + nx + n be α and β.
माना समीकरण lx2 + nx + n के मूल α और β हैं ।
,,
