Question 2

In the following question, find out which part of the sentence has an error. If the sentence is grammatically correct, mark your answer as 'No Error'.My favourite teacher has (A)/ taught me very well how to write and speak English (B)/ and French in a very short (C) span of time (D) No Error (E)

The sentence is grammatically correct and well-structured. All parts flow logically without any errors in tense, subject-verb agreement, or preposition usage.

Question 3

Directions: Instructions
In the given questions, two quantities are given, one as Quantity I  and another as Quantity II. You have to determine relationship between two quantities and choose the appropriate  option.
a: If quantity I ≥ quantity II
b: If quantity I > quantity II
c: If quantity I < quantity II
d: If quantity I = quantity II or the relationship cannot be  established from the information that is given
e: If quantity quantity I

1 > a > 0 > bQuantity:1. value of(a+b)2−a2−b2(a+b)2−(a2−b2)=12(ab3+ab)

Accepted Answer

Simplify Quantity I: (a+b)^2 - (a^2 - b^2) = 2ab + 2b^2. Simplify Quantity II: 1/2(ab^3 + ab) = ab/2(b^2 + 1). Since 'b' is negative, the relationship cannot be established.

Question 4

Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.You, I and Ram (A) went to the market (B) the day before yesterday (C)where we bought this pillow (D)/ No error (E)/

Accepted Answer

The correct order for pronouns in a sentence when referring to multiple people is 2nd person, 3rd person, then 1st person (231 rule). So, 'You, Ram and I' is correct.

Question 5

In the question below, a part of the sentence is underlined. Below are given alternatives to the underlined part which may improve the sentence. Choose the correct alternative. In case no improvement is needed, choose 'No improvement'.​The new sofa isvery nicerthan the old one.

Accepted Answer

The comparative adjective 'nicer' requires an intensifier like 'much' or 'far,' not 'very.' 'Much nicer' correctly expresses a significant difference.

Question 6

Directions: Instructions
In the given questions, two quantities are given, one as Quantity I  and another as Quantity II. You have to determine relationship between two quantities and choose the appropriate  option.
a: If quantity I ≥ quantity II
b: If quantity I > quantity II
c: If quantity I < quantity II
d: If quantity I = quantity II or the relationship cannot be  established from the information that is given
e: If quantity quantity I

There are three positive numbers- a, b and c. The average of a and b is less than the average of b and c by 1.Quantity :I. Value of c.II. Value of a

Accepted Answer

Given (a+b)/2 = (b+c)/2 - 1. Multiply by 2: a+b = b+c-2. Subtract b from both sides: a = c-2. This implies c = a+2. Since a is positive, c must be greater than a.

Question 7

In the following sentence, some parts have error and some are correct. Find out which part has an error and mark it as your answer. If there is no error, mark ‘No error’ as your answer.After a long wait (A) of almost 68 years, (B) the jury gave their verdict (C) on the Ayodhya feud. (D)No Error. (E)

Accepted Answer

The collective noun 'jury' should be treated as singular when acting as a single unit. Therefore, 'its' (singular possessive) should be used instead of 'their' (plural possessive).

Question 8

Directions: Instructions
In the given questions, two quantities are given, one as Quantity I  and another as Quantity II. You have to determine relationship between two quantities and choose the appropriate  option.
a: If quantity I ≥ quantity II
b: If quantity I > quantity II
c: If quantity I < quantity II
d: If quantity I = quantity II or the relationship cannot be  established from the information that is given
e: If quantity quantity I

Three equal circles are drawn on a triangle ABC, with points A, B and C as the centres. Radius of each of the circle is equal to half of the side of the triangle ABC. (Figure not to the scale)Area of shaded region 1 =12813cm2Quantity :I. The area of the shaded region 2 ( in cm‌2)II. 30 cm‌2

Accepted Answer

The shaded regions are sectors of equal circles. Since the triangle is equilateral (implied by equal radii and symmetry), all angles are 60 degrees. Thus, all shaded sectors have equal areas. So, Quantity I = 128/3 cm² ≈ 42.67 cm². Comparing with Quantity II (30 cm²), Quantity I > Quantity II.

Question 9

Directions: Ques No: 13-20
Parents prefer private schools. A global survey in 2017 found that they were a lot more likely to give the teaching at their children’s school a positive rating if it was private than if it was public;
parents in Chile have voted with their children’s feet in favour of the private sector
. The private sector’s efficiency is one reason why it does well at providing access to education. Another is its speed: in fast-growing cities, governments struggle to provide schools, but wherever there are people, schools spring up.
Governments are often less keen on private education. Some of the reasons for their hostility are bad ones: a reluctance to
cede
power, the opportunity for patronage, the influence of teachers’ unions. But some are entirely in order: governments need to promote quality, access to schooling and equity. The private sector is
good
at some, but not all, of those. Yet well-designed public-private partnerships can work. Two of the world’s best education systems—those of the Netherlands and Hong Kong—are based on them.
The main reason for the private sector’s superior efficiency seems to be teachers, who are paid less and are more likely to turn up for work than at government schools. Politics has a lot to do with that. Teachers’ unions have huge bargaining power and can, therefore, protect their members from being held to account for poor performance. An Indian study found that in 3,000 government schools, only one principal had ever dismissed a teacher; among 600 private schools, 35 had.

Which of the following is TRUE based on the above passage?

Accepted Answer

The passage likely discusses the potential benefits of well-designed public-private partnerships in education, making option 4 a direct and positive inference.

d: If quantity I = quantity II or the relationship cannot be  established from the information that is given
e: If quantity quantity I

Ram invested P in scheme A and 2P in scheme B, for two years each. Scheme A offers simple interest p.a. Scheme B offers compound interest (compounded annually) at the rate of 10% p.a. Respective ratio between the interest earned from scheme A and that earned  from scheme B was 8 : 21.Quantity :I. Rate of interest offered by scheme A.II. Rate of interest offered by scheme C (simple interest p.a.),  when 1,600/- is invested for 3 years earns an interest of 384/-.

Accepted Answer

Calculate interest from Scheme B: CI = 2P[(1+0.10)^2 - 1] = 0.42P. Given ratio 8:21, SI from A = (8/21)*0.42P = 0.16P. Rate for A = (0.16P / (P*2)) * 100 = 8%. For Quantity II, rate = (384 / (1600*3)) * 100 = 8%. Thus, Quantity I = Quantity II.

Question 11

In the following question, out of the five alternatives, select the alternative which will improve the underlined part of the sentence. In case no improvement is needed, select the "No improvement" option.When the crowd collected round him he seemed confused, but at the demand of the tall lad who had pushed his way up to him, hebegan in a fairly too tremulous voiceto read the sheet from the beginning.

Accepted Answer

The phrase 'fairly too' is grammatically incorrect. 'Rather too' is the correct idiomatic expression to indicate an excessive degree, making option 3 the best improvement.

Question 20

The simple interest accrued on an amount of Rs 84,000 at the end  of three years is Rs. 30,240 What would be the compound interest accrued on the same amount at the same rate in the same period ?

Accepted Answer

First, calculate the simple interest rate (R) using SI = PRT/100. Then, use this rate to calculate the compound interest (CI) for the same principal and time using CI = P[(1 + R/100)^T - 1].
