Correct Answer : A

The average height of the boys is 160.5 cm. Take 4 boys and 5 girls (girls are 25 % more). Let the boys' average be b, so the class average is b - 2.5. Total height: \[5(156) + 4b = 9(b - 2.5)\] \[780 + 4b = 9b - 22.5\] \[5b = 802.5\] so b = 160.5. Check: the class average is 158, and (780 + 642)/9 = 158. The other options do not satisfy the condition that the boys' average is 2.5 cm above the class average.

Correct Answer : B

Work forwards from cost to selling price, then backwards from selling price to the advertised (marked) price.

\[ \text{SP} = 900 \times 1.10 = \text{Rs. } 990 \]

The 12% discount is taken off the advertised price, so

\[ \text{MP} \times (1 - 0.12) = 990 \]

\[ \text{MP} = \frac{990}{0.88} = \text{Rs. } 1125 \]

Profit is reckoned on the cost price and discount on the marked price - two different bases, which is why they cannot be netted off against each other.

Correct Answer : A

Any prime number greater than 3 will be in the form of 6x+1 or 6x−1.

Thus, both prime number are twins:

Let first be 6x−1
and 2nd be 6x+1
Sum=12x

Thus it is always divisible by 12.

Correct Answer : C

Let the age of A = \(A\), B = \(B\) and C = \(C\)

From given,

\(A = 3B\)

4 years ago,

\(A + 4 = 31\)

\(\Rightarrow A=27\)

sub in above \(B\) , we get \(B\)  = 9 

\(C = 2(27 - 4) + 4 = 46 + 4 = 50 \)

Hence B = 9years and C = 50years.

Correct Answer : B

The statement requests people not to use lift while moving down. This implies that the lift may be used to move up and the request has been made so that more people can use the lift for ascending which would otherwise cause more physical stress than going down the stairs. So, only II is implicit.

Correct answer: C

Separating alternate terms gives M, N, O in the odd positions and A, B in the even ones, each advancing by one. The next term is the third of the second series, which is C. Interleaved series are recognised by the terms alternating between two widely separated parts of the alphabet. P is the tempting answer because it continues the series the eye follows most readily, but it belongs to the wrong strand. The two strands here start far apart, at M and at A, which is what makes the alternation visible at a glance rather than needing the terms to be separated first.

Correct Answer : C

Let the number of boys and girls participating in sports be 3x and 2x respectively.

Then, 3x = 15 or x = 5.

So, number of girls participating in sports = 2x = 10.

Number of students not participating in sports = 60 - (15 + 10) = 35.

Let number of boys not participating in sports be y.

Then, number of girls not participating in sports = (35 -y).

Therefore (35 - y) = y + 5 

\(\Rightarrow  2y = 30\) 

\(\Rightarrow  y = 15.\)

So, number of girls not participating in sports = (35 - 15) = 20.

Hence, total number of girls in the class = (10 + 20) = 30

Correct Answer : C

Correct answer: were

In a hypothetical or contrary-to-fact condition, the verb be takes the subjunctive form were for every subject, including I, he, she and it. Hence if I were in his place. This is the second conditional, whose pattern is if + past tense in the condition and would + bare infinitive in the result - and the result clause here, I would resign, is already correct. The subjunctive is used only where the situation is imagined or known to be untrue. Where the condition might genuinely be so, the ordinary past is correct: if he was at home yesterday, he must have heard. The form survives in a handful of set expressions worth knowing together: if I were you, I wish I were taller, he talks as if he were the owner, and were it not for your help. Had been would shift the sentence into the third conditional and change its meaning to a lost past opportunity.

Correct answer: However, even if those figures are not accurate, the construction of the pyramids was an amazing achievement

The blank sits between Herodotus's figures and a description of how the stones were actually moved. However and those figures both point back to the numbers just given, and the claim of an amazing achievement is what the description of ramps and rollers goes on to support. The other options are facts about Egyptian religion and daily life that the paragraph never uses.

Correct Answer : D

Correct answer: mercy is the noblest form of revenge.

The passage sets forgiveness against vengeance throughout: yielding to resentment is easy, restraining it takes a strong character, and the man who forgives proves himself the superior of the wrongdoer and puts him to shame.

That last clause is decisive. Forgiveness here is not merely kind - it defeats the offender more completely than retaliation would, which is exactly what calling mercy a form of revenge means.

Correct Answer : D

The meaningful order is CADB.

The paragraph reads: 'We cannot go through life without sorrow and suffering (C). Although life is complex and mysterious (A), no man can be discontented (D) who does his duty (B).'

C is a complete opening statement. A, beginning with Although, is a subordinate clause that needs a main clause, which D supplies. B, beginning with Who, is a relative clause that must follow the noun it describes, man in D, so it comes last. ACDB separates A from D. ADCA repeats A and leaves out B. CDBA puts the Although clause at the end with nothing to qualify.

Harike barrage is at the confluence of the Satluj and Beas.

The barrage at Harike in Punjab is built just below the point where the Beas joins the Satluj. The Indira Gandhi Canal (Rajasthan Canal) takes off from it and carries water into the Thar.

The Jhelum and Ravi do not meet the Satluj at Harike: the Jhelum flows through Pakistan, and the Ravi joins the Chenab there.

Correct answer: 12

The Constitution now has 12 schedules. It began with eight, and four have been added by amendment. They are worth knowing in outline. The First lists the states and union territories. The Second sets out the emoluments of the President, Governors, judges and the CAG. The Third gives the forms of oath. The Fourth allots Rajya Sabha seats to the states. The Fifth and Sixth deal with the administration of scheduled areas and tribal areas, the Sixth applying to Assam, Meghalaya, Tripura and Mizoram. The Seventh contains the three legislative lists. The Eighth lists the 22 languages. The four added later are the Ninth (1951, laws immune from judicial review), the Tenth (1985, anti-defection), and the Eleventh and Twelfth (1992, the subjects devolved to panchayats and municipalities). The Ninth Schedule’s immunity is no longer absolute: the Supreme Court held in 2007 that laws placed in it after 1973 can still be tested against the basic structure.

Correct Answer : B

Correct answer: The Weimar Constitution of Germany

The emergency provisions, and in particular the suspension of fundamental rights during an emergency, were drawn from the Weimar Constitution of Germany. The borrowing is a cautionary one, since Article 48 of the Weimar Constitution - the emergency power - was the instrument through which the Weimar Republic was dismantled in 1933. Members of the Constituent Assembly raised precisely this objection, and Ambedkar defended the provisions on the ground that the safeguards and the accountability of the executive to Parliament would prevent abuse. The Emergency of 1975–77 vindicated the critics to a degree, and the 44th Amendment of 1978 tightened the provisions substantially: internal disturbance was replaced by armed rebellion, written Cabinet advice was required, parliamentary approval was made harder and periodic, and Articles 20 and 21 were made non-suspendable. The other constitutions named contributed elsewhere - fundamental rights from the United States, directive principles from Ireland, and a strong centre from Canada.

Bihar and Orissa are the richest in iron ore.

The Singhbhum-Keonjhar-Mayurbhanj belt straddling the two holds high-grade haematite of over 60 per cent iron, and feeds the steel plants at Jamshedpur, Bokaro and Rourkela. The Bihar portion has lain in Jharkhand since 2000.
