Answers:

1) Answer: C

secθ=13/12 [Triplet, 5, 12, 13]

cotθ=(12/ 5) & tanθ= (5/12)

So, √(cotθ+tanθ)=√(12/5+5/12)=13/√60

=13/(2√15)

2) Answer: C

(1+tan θ) = secθ = 625/49

sec θ = 25/7

sin θ = 24/25

cos θ = 7/25

√sin θ  + cos θ

= √31/5

3) Answer: B

sin θ = (1 – sin2 θ)

sin2 θ = cos4 θ

1 – cos2 θ = cos4 θ

1 = cos4 θ + cos2 θ

1 = (cos4 θ + cos2 θ )3

1 = cos12 θ + 3 cos10 θ + 3 cos8 θ + cos6 θ

cos12 θ + 3 cos10 θ + 3 cos8 θ + cos6 θ – 1 = 0

4) Answer: B

cot θ = √11 ⇒ cot2 θ = 11

(cosec2 θ + sec2 θ) /(cosec2 θ – sec2 θ) = 1/(cos2 θ – sin2 θ) = 1/ (cos 2θ) = 1/(2 cos2θ – 1)

cos2 θ = 1/2 ⇒ (1/(2×(1/2)-1)) = -(6/5)

5) Answer: B

put θ = 45°(cos θ/(1+sin  θ)) + (cos θ/(1- sin  θ)) = 2 √2

6) Answer: D

No. of cars = (40600/90) 30=13500

7) Answer: B

Required ratio = 40500/33750 = 162/135 = 6/5

8) Answer: A

Required No. of models cars = 810 × 360 = 291600

9) Answer: C

Difference in the no. of ears = 200 × 5 = 1000

10) Answer: B

100% of E = 15000

E =  15000/75×360

⇒72000/5=14400
