**SSC CGL Quantitative Aptitude Questions – Important ****Geometry Questions**

**SSC CGL Quantitative Aptitude Questions – Important**

**Geometry Questions**

**Q1) In a Δ ABC, if D and E are the points on the sides AB and AC respectively such that DE || BC and if AD = x , DB = x – 2 , AE = x + 2 and EC = x – 1. then find the value of x.**

A. 5

B. 4

C. 3

D. 2

Answer: Option B

**Explanation: **

**Since DE || BC**

Therefore, AD/DB = AE/EC

⇒ x/x-2 = x+2/x-1

⇒ x^{2} – x = x^{2} – 4

⇒ x(x –1) = (x +2)(x –2)

⇒ x = 4

Hence, option B is correct**.**

**Q2) ****In ΔABC, AB = AC, ∠B = 70°, ∠BAD = 80°, ∠ADE = ?**

Explanation:

∠B = ∠ACB = 70°

∠ADE = ∠CAD + ∠ACD = 40° + 110° = 150°

Hence, option A is correct.

**SSC CGL Quantitative Aptitude Questions – Important ****Trigonometry Questions**

**SSC CGL Quantitative Aptitude Questions – Important**

**Trigonometry Questions**

**Q1)** **If cosΘ = – 1/2 and π < Θ < 3π, find the value of 4 tan ^{2}Θ – 3 cosec^{2}Θ**

A. 12

B. 8

C. 4

D. 2

Correct Answer: Option B

**Explanation: **

**B**

We know that

sinΘ = ± 1 – cos^{2}

or, sinΘ = 1-1/4 = 3/2

Since Θ lies in the third quadrant, the value of sinΘ is negative.

or, cosecΘ = -2/3

and tanΘ= sinΘ/cosΘ = 3

Since Θ lies in the third quadrant, the value of tanΘ is positive.]

Now, 4 tan^{2}Θ – 3 cosec^{2}Θ = 4 × 3 – 3 × 4/3 = 8

**Q2) If 8 sin x = 4 + cos x, the values of sin x are :**

A. 3/5, -5/13

B. -3/5, 5/13

C. -3/5, -5/13

D. 3/5, 5/13

**Correct Answer: Option D**

**Explanation:** 8 sin x – 4 = cos x ⇒ 8 sin x – 4 = 1- sin^{2} x

⇒ sin x = 3/5 or sin x = 5/13

⇒ 1 – sin^{2} x = (8 sin x – 4)^{2}

⇒ 1 – sin^{2} x = 64 sin^{2} x + 16 – 64 sin x

⇒ 65 sin^{2} x – 64 sin x + 15 = 0

⇒ 65 sin^{2} x – 39 sin x – 25 sin x + 15 = 0

⇒ 13 sin x (5 sin x – 3) – 5 (5 sin x – 3) = 0

⇒ (5 sin x – 3) (13 sin x – 5) =0

therefore, sin x = 3/5 or 5/13
