ANSWER KEY:
Q1. (C)
part of the distance is covered in 10 minutes.
दूरी का भाग 10 मिनट में तय किया जाता है । 
part of the distance will covered in/दूरी का भाग तय किया जाएगा =

= 48 minutes/मिनट

Q2. (C) a + b = – c, b + c = – a, c + a = – b
(– c – c)2+ (– a – a)2 + (– b – b)2 = 4a2 + 4b2 + 4c2

Q3. (B) 15 ............ A + B + C ... 2
5 ............... A ................. 6
6 ............... B ................. 5 
Hence/अतः, C = 15 – 5 – 6 = 4 
Time taken by C to complete the work/C द्वारा कार्य को पूरा करने में लिया गया समय 
= hours/घंटे

Q4. (B) CP = 100%
SP = 90% if 10% loss/यदि 10% की हानि हुई है ।
SP = 110% if 10% profit/यदि 10% का लाभ हुआ है ।
20% = 108
100% = Rs./रु.540

Q5. (B) Principal/मूलधन = Rs./रु.800
Increased amount is/बढ़ी हुई धनराशि है = of/का 800
New amount/नया मिश्रधन = Rs./रु.956 + Rs./रु.96 = Rs./रु.1052

Q6. (A) a = k, b + c = 3k
a + b + c = 4k
a + b =
c = (a + b + c) – (a + b)
= 4k – =
a + c = k +=
b = (b + c) – c
= 3k – =
b : (a + c) = 1 : 2

Q7. (C) Total c.p./कुल क्रय मूल्य = Rs./रु.1600 + Rs./रु.2400 = Rs./रु.4000
Discount/छूट% = 10%

Profit/लाभ% =

Q8. (C) 

Q9. (A) 00 α < 600 Let α = 300
sin 300 sec (300 + α) = sin300. sec 600 = 1
sin 300 + cos 2(300) = 1
sin300 + cos 600 =

Q10. (C) cos θ + sec θ = 2
cos θ + 1/cos θ = 2
cos2 θ + 1 –2cos θ = 0
(cos θ – 1)2 = 0
cos θ = 1
θ = 0
cos10 θ + sec11 θ = 1 + 1 = 2
