Rearrange the parts of the sentence in correct order.Williamson shoveled scorn onP-the low-income white Republican voters who, Q-were  most responsible for the rise of TrumpR-as he saw it,

Accepted Answer

The sentence starts with 'Williamson shoveled scorn on'. 'P' logically follows, identifying 'the low-income white Republican voters'. 'R' then clarifies 'as he saw it', referring to Williamson's perspective. Finally, 'Q' completes the thought, explaining what those voters 'were most responsible for'.

Question 2

Select the antonym of coalesce

Accepted Answer

Coalesce means to come together and form one mass or whole. Therefore, its antonym is 'separate,' meaning to divide or disconnect.

Question 3

Improve the bracketed part of the sentence.The public vent their anger on social media to protest  (toward) police brutality.

Accepted Answer

The correct preposition to express opposition or disagreement is 'against'. People protest against something they disapprove of, making 'against' the most suitable choice here.

Question 4

Ifcot2A−cos2A=x, then value of x is

Accepted Answer

Rewrite cot²A as cos²A/sin²A. Factor out cos²A, leaving (1/sin²A - 1). Simplify to cos²A(1-sin²A)/sin²A, which is cos²A(cos²A/sin²A) or cot²Acos²A.

Question 5

Which of the following equations has the sum of its roots  as 7?

Accepted Answer

For a quadratic equation ax²+bx+c=0, the sum of roots is -b/a. In option 2, x²-7x+10=0, a=1, b=-7. So, sum of roots = -(-7)/1 = 7.

Question 6

The price of an article is cut by 7%, to restore it to its  original value, the new price must be increased by

Accepted Answer

Let original price be 100. After 7% cut, new price is 93. To restore 100 from 93, increase needed is (7/93)*100 = 7.53%.

Question 7

Select the synonym ofproximity

Accepted Answer

Proximity means nearness in space, time, or relationship. Imminent means about to happen, or close at hand. Thus, 'imminent' is the closest synonym.

Question 8

The phrase 'since early morning' indicates an action that started in the past and is continuing in the present. This requires the present perfect continuous tense, which is 'have been queuing up'.

Question 9

Select the antonym of loiter

Accepted Answer

To 'loiter' means to stand or wait around idly. The antonym is 'hasten', which means to move or act quickly.

Question 10

What are the coordinates of the centroid of a triangle, whose vertices are A(-2,5), B(4,4) and C(7,-3)?

Accepted Answer

The centroid coordinates are found by averaging the x-coordinates and y-coordinates separately. Sum the x-values (-2+4+7=9) and divide by 3 (9/3=3). Sum the y-values (5+4-3=6) and divide by 3 (6/3=2). Thus, the centroid is (3,2).

Question 11

(cosecA - sinA)(secA - cosA)(tanA + cotA) is equals to

Accepted Answer

Convert all terms to sinA and cosA. Simplify each bracket: (1-sin²A)/sinA, (1-cos²A)/cosA, (sin²A+cos²A)/(sinAcosA). Multiply them to get (cos²A/sinA) * (sin²A/cosA) * (1/sinAcosA) = 1.

Question 12

A bag has Rs12.9 in the form of 1 rupee, 50 paise and 10  paise coins in the ratio of 3:2:3. How many 50 paise coins are there in the bag?

Accepted Answer

Convert all values to paise. Let the number of coins be 3x, 2x, 3x. Total value: 3x(100) + 2x(50) + 3x(10) = 1290. Solve for x, then find 2x.

Question 13

In the following question, a sentence has been given in  Active/Passive voice. Out of four alternatives suggested, select the one, which best expresses the same sentence in Passive/Active voice.We have finished the assignment.

Accepted Answer

The active sentence is in the present perfect tense. To convert it to passive voice, use 'has/have been' + past participle. 'The assignment' is singular, so 'has been finished' is correct.

Question 14

In a triangle the length of the side opposite the right angle is 6 cm, what is the length of the side opposite to the angle which measures 30°?

Accepted Answer

In a 30-60-90 triangle, the side opposite the 30° angle is half the hypotenuse. Given hypotenuse is 6 cm, so the side opposite 30° is 6/2 = 3 cm.

Question 15

x and y are two numbers such that their mean proportion  is 6 and third proportion is 48. What is the value of x and y?

Accepted Answer

Mean proportion of x and y is sqrt(xy) = 6, so xy = 36. Third proportion is y^2/x = 48. Substitute x = 36/y into the second equation to find y=12, then x=3.

Question 16

Which of the following equations has the sum of its roots as 11?

Accepted Answer

For a quadratic equation ax^2 + bx + c = 0, the sum of roots is -b/a. In option 1, -(-11)/1 = 11.

Question 17

Rearrange the parts of the sentence in correct orderThe truth about these P-communities is that Q-they  deserve to dieR-dysfunctional, downscale
