SSC CGL Tier 1 Mock Test - 19 - SSC CGL MCQ

The pattern of the series is:

227 − 1× 6 = 221

221 – 2 × 5 = 211

211 – 3 × 4 = 199

199 – 4 × 3 = 187

187 – 5 × 2 = 177

As

1×2×3×4 = 24

Similarly

3×1×5×4 = 60

Given equation: 17 - 20 + 5 × 30 ÷ 4 = ?

After replacing the signs:

⇒ 17 × 20 ÷ 5 - 30 + 4

Solving by using the BODMAS rule,

= 17 × 4 - 30 + 4

= 68 - 30 + 4

= 42

Concept used:

Sum of all the angles of a quadrilateral is 360°

Calculation:

Let's assume that, each of the three equal angles be k, then

3k + 120 = 360

⇒ 3k = (360 - 120)

⇒ k = 240/3 = 80° 

∴ The value of each equal angle is 80° 

Rise in 2015 - 16 = 53 - 51 = 2
Rise in2016 - 17 = 65 - 53 = 12
Rise in 2017 - 18 = 76 - 65 = 11
Rise in 2019 - 20 = 68 - 58 = 10
Rise in2020 - 21 = 73 - 68 = 5
∴ Maximum rise in production of wool is in 2016 - 17.

Let each of them earn 8x and 5x respectively.
Income - Expenditure = saving
According to question
8x - 200 = 10x - 400
8x - 200 = 10x - 400
2x = 200
x = 100
So, salary of A and B is Rs 800 and Rs 500 respectively.

(0.04)⁵ × (0.2)⁴ ÷ (0.008)² = (0.2)ˣ
(0.2²)⁵ × (0.2)⁴ ÷ (0.2³)² = (0.2)ˣ
(0.2)¹⁰⁺⁴⁻⁶ = (0.2)ˣ
(0.2)⁸ = (0.2)ˣ
x = 8

Let us evaluate the individual net worth of the sons according to the current valuation of the stakes

Elder Son net worth:

Net worth = Stake + Assets

⇒ Net worth =45% of the total stakes + Asset

⇒  Net worth 

⇒ Net worth = 13.5 + 5.5 

⇒ Net worth =19 billion dollars

Younger Son net worth:

Net worth = Stake + Assets

⇒ Net worth = 55% of the total stakes + Asset

⇒ Net worth 

⇒ Net worth = 16.5 + 3.5 

⇒ Net worth = 20 billion dollars

∴ The younger son is richer by 1 billion dollars.

To find the length of the wire, we need to use the principle of conservation of volume. The volume of the metallic sphere will be equal to the volume of the wire it is drawn into.
1. Volume of the Sphere:

2. Volume of the Wire:

3. Equating the Volumes:

4. Solving for the Length h:

So, the length of the wire is:

Therefore, the correct option is:

Given:
= 1:12:13 = 6:3:2
The ratio of initial investments
Let their initial investments be 6x, 3x, and 2x respectively.
We know:
When investments of all the partners are for the same time, the gain or loss is distributed among the partners in the ratio of their investments.
According to the question:
A: B: C = (6x × 4 + 3x × 8): (3x × 12): (2x × 12)
= (24x + 24x): 36x: 24x
48x: 36x: 24x = 8:6:4
= 4:3:2
B 's share =Rs. (450 × 39) = Rs. 150

Area of equilateral triangle  

a = 44 cm

The perimeter of an equilateral triangle = 3 x sides of an equilateral triangle

⇒ 44 x 3 ⇒​​​​​​​ 132i.e. perimeter of the circle so formed

The perimeter of a circle = 2πr

 ; (given)

r = 21cm

Let A(1, 1), B(-2, 7) and C(3, 3) are the given points. Then we have

and 

Clearly BC = AB + AC         

∴ A,B, C are collinear.

If, 

Let  and 

We know, 

According to the question, 

Total cost price (C.P.) of book = 500 + 25 + 50 = Rs. 575 

Therefore, the selling price of the book to earn 16% profit of C.P.

= Rs. 667
