The new fraction of basmati rice in the mixture = 80% ⇒ 4/5

⇒ (48 + x)/(80 + x) = 4/5

⇒ 240 + 5x = 320 + 4x

⇒ x = 80 kg

The correct option is 3.

Concept used:

Solution

⇒ (4/3) × 24 + [7 + (1/8) × 128 + (1/6) × 144 - (1/2) × 14] 

⇒ (4/3) × 24 + [7 + 16 + 24 - 7] 

⇒ (4/3) × 24 + [40]

⇒ 32 + [40]

⇒ 72.

The correct option is 2.

Given

Kamal can do a piece of work = 18 days 

Kamlesh can do the same work = 36 days

Formula

Efficiency = Total work/time taken

Solution

Let the total work be 36 units(LCM of 18 and 36)

Efficiency of kamal = 36/18

⇒ 2 units/day

Efficiency of kamalesh = 36/36

⇒ 1 units/day

Efficiency of Sunil = 36/6

⇒ 6 units/day

Work done together in 6 days = (1 + 2) × 6

⇒ 18 units

Remaining work = 36 - 18

⇒ 18 units

The together complete the remaining work in:

⇒ 18/(1 + 2 + 6)

⇒ 2 days

The total number of days in which they complete the work:

⇒ 6 + 2 = 8 days

The correct option is 3.

Given

The area of a trapezium shaped field = 400 

The distance between two parallel sides = 20 m

One of the parallel sides = 16 m

Formula

The area of a trapezium = 1/2 × (sum of parallel sides) × distance between them

Solution

Let one of the side be a cm.

⇒ 400 = 1/2 × (16 + a) × 20

⇒ 40 = 16 + a

⇒ a = 24

The correct option is 1.

Solution

The LCM of 5, 18 and 15 = 90

The resulting number should be:

⇒ 90k + 7

On dividing 1736 by 90k, we get quotient = 181 and the remainder = 26

The remainder in each case should be 7 and hence we subtract:

⇒ 26 - 7 = 19

The least number subtracted = 19

The correct option is 3.

Given

Presently, the ratio of ages of Bhoomi and Som = 7 : 3 

Bhoomi's age 4 years ago and Som's age 4 years hence = 2 : 1

Solution

Let the present age of Bhoomi and Som be 7x and 3x.

⇒ (7x - 4)/(3x + 4) = 2/1

⇒ 7x -  4 = 6x + 8

⇒ x = 12

The present age of Bhoomi and Som :

⇒ 84 years and 36 years

The ratio Bhoomi's age 4 years hence and Som's age 4 years ago:

⇒ 88: 32 

⇒ 11: 4

The correct option is 1.

Given:

Speed in still water = u = 9 kmph

Speed of river = v = 3 km/hr

Concept used:

Speed in downstream = d = u + v

Speed in upstream = p = u - v

Average speed = 2dp/(d + p)

Solution:

d = 9 + 3 = 12 kmph

p = 9 - 3 = 6 kmph

Average speed = (2 x 12 x 6)/(12 + 6) = 8 kmph

Hence, the correct option is 2.

Given

The ratio of the present ages of a husband and wife = 7: 5

Solution

Let their present age be 7x and 5x.

⇒ (7x + 10)/(5x + 10) = 9/7

​⇒ 49x + 70 = 45x + 90

​⇒ 4x = 20

​⇒ x = 5

So, there present age are 35 and 25

Since the gap between them is of 10 years it will remain constant .

At time of their marriage, their ages were 5y and 3y

⇒ 5y - 3y = 10

⇒ 2y = 10

⇒ y = 5

So their age at the time of marriage will be 25 and 15

So child is born when they were 27 and 17 and now they are 35 and 25 so the age of son is 8 years.

The correct option is 2.

Concept used:

Solution

⇒ 60% of 150 + 26% of 765

⇒ 90 + 198.9

⇒ 288.9

⇒ 289

The correct option is 2.

Solution:

Weight of Ross in class 9^th = 72 kg

Weight of Rachel in class 9^th = 48 kg

Weight of Monica in class 10^th = 82 kg

Weight of Phoebe in class 10^th = 58 kg

Sum of weight of Ross and Rachel in class 9^th = 72 + 48 = 120 kg

Sum of weight of Monica and Phoebe in class 10^th = 82 + 58 = 140 kg

Required Ratio = 120 : 140 = 6 : 7

Hence, the correct option is 1.

Given

The average age of the boys in the class = 12 years

The average age of the girls in the class = 16 years

Formula used

Average = Total sum of all values/No.of values

Solution

Total sum of all boys = 30 × 12 = 360

The total sum of all girls = 20 × 16 = 320

Total sum of class = 360 + 320 = 680

Average of class = 680/50

⇒ 13.6 years

The correct option is 2.

Given

The total students appearing in school X = 660

The total students appearing in school Y = 580

Solution

No.of girls students appearing in school X = ​40% of 660

⇒ 4 × 66

No.of girls appearing in school Y = ​60% of 580

⇒ 6 × 58

The ratio of the number of girls appearing in school X to the number of girls appearing in school Y is,

⇒ 4 × 66: 6 × 58

⇒ 22: 29

The correct option is 4.

Given

The radius of the circular field = side of a square field

The area of the circular field - the area of the square field = 105 sq. m

Formula used

Area of square = a²

where, a = side of square

Area of circle = πr²

where, r = radius of circle

Solution

⇒ πr² - a² = 105

⇒ a = r(as given)

⇒ πa² - a2 = 105

⇒ a²(22/7 -1) = 105

⇒ a² = 105 × 7/15

⇒ a2 = 49

⇒ a = 7 (a = r)

The perimeter of the circular field = 2πr

⇒ 2 × 22/7 × 7

⇒ 44 m

The correct option is 1.

सही उत्तर: 'विजय का दूसरा नाम संघर्ष' है।

• यह गद्यांश संघर्ष से विजय प्राप्त करने की प्रक्रिया, और समस्याओं के प्रति सामर्थ्य और दृढ़ता का महत्व बताता है, जो सीधे तौर पर विजय के प्राप्ति के साथ सम्बंधित है।

Key Pointsअन्य विकल्पों की व्याख्या:

• अनावश्यक संघर्ष - यह गद्यांश मानव संघर्ष की अनिवार्यता पर बल देता है, इसलिए यह विकल्प उपयुक्त नहीं है।
• संघर्ष से डरना - गद्यांश जीवन में संघर्ष की आवश्यकता और महत्व बता रहा है, डर तो समस्याओं को नकारने की शक्ति बताता है, जो मूल वचन से मिलता नहीं है।
• न विजय न संघर्ष - यहां गद्यांश वीरता, कठिनाईयों का सामना करने, और जीवन में सफलता प्राप्त करने का प्राथमिकता है। उपर्युक्त विकल्प संघर्ष का निषेध करता है, जो गद्यांश के संदेश से मेल नहीं खाता।

सही उत्तर: "संघर्ष" है।

• प्रत्येक समस्या के साथ एक व्यक्तिगत या सामूहिक संघर्ष आता है, जैसा कि हमें समस्या से निपटने में मदद करने के लिए आत्म संवेदनशीलता, समाधान, और तत्परता को उभारने की आवश्यकता होती है।

Key Pointsअन्य विकल्पों की व्याख्या:

• मानवीय गुण - समस्याएं हमें अपने मानवीय गुणों को पहचानने और विकसित करने में मदद करती हैं, लेकिन वे स्वयं उन्हें नहीं लेकर आती।
• जीवन - समस्याएं जीवन का हिस्सा हैं, लेकिन वे स्वयं जीवन नहीं होतीं।
• लगन - समस्याओं को हल करने के लिए लगन और समर्पण की आवश्यकता होती है, लेकिन वे खुद लगन नहीं लेकर आती।

सही उत्तर: "परिश्रम, दृढ़ इच्छा शक्ति व लगन" - यह तीनों गुण संघर्ष को सफल बनाने वाले महत्त्वपूर्ण तत्व होते हैं।

• इन्हें अवलंबन करके ही व्यक्ति संघर्ष में खुद को सशक्त बना सकता है और इस प्रकार जीवन में सफलता प्राप्त करने का मार्ग प्रशस्त होता है।

Key Points

अन्य विकल्पों की व्याख्या:

• परिश्रम, कमजोर इच्छा शक्ति व लगन - कमजोर इच्छा शक्ति संघर्ष और सफलता के मार्ग को प्रशस्त नहीं कर सकती।
• बाहरी शक्ति - जीवन के संघर्ष में सफल होने के लिए, बाहरी शक्ति की अपेक्षा व्यक्ति की अन्तरात्मा और प्रयास की अधिक आवश्यकता होती है।
• परिश्रम, दृढ़ इच्छा शक्ति व कार्य न करने की लगन - कार्य न करने की लगन संघर्ष और सफलता के मार्ग को प्रशस्त नहीं कर सकती।

सही उत्तर: विकल्प 

• संकल्प का अर्थ होता है एक ठोस निर्णय या समर्पित इच्छा, जबकि "विकल्प" का अर्थ होता है किसी मुद्दे या समस्या के साथ-साथ संभव समाधानों या पथों का चयन।

• इच्छाशक्ति - इच्छाशक्ति संकल्प को भी व्यक्त करती है, जिसका अर्थ होता है किसी विशिष्ट कार्य की पूरी करने की ज़ोरदार इच्छा या चाहत।
• इरादा - इरादा संकल्प के समान होता है, जिसका अर्थ होता है एक ठोस निर्णय या संकल्पना, किसी विशेष उद्देश्य या लक्ष्य की ओर जाने की इच्छा।

सही उत्तर: संघर्ष से डरना या विमुख होना नहीं चाहिए।

समस्त ग्रंथों और व्यक्तिगत अनुभवों के आधार पर, जब संघर्ष का सामना करने का समय आता है, हमें डरने या उससे विमुख होने की बजाय इसका सामना करना चाहिए।

Key Points

अन्य विकल्पों की व्याख्या:

• संघर्ष नहीं करना चाहिए - यह विकल्प तर्कसंगत नहीं है क्योंकि ग्रंथों और अनुभवों से प्राप्त ज्ञान संघर्ष की अहमियत को समझाता है।
• संघर्ष से लड़ना या विमुख होना नहीं चाहिए - संघर्ष से लड़ना तो बहुत ही आवश्यक है, लेकिन विमुख होने का विचार गलत है क्योंकि यह सामर्थ्यता और विकास को बाधित करता है।
• चुनौतियों का सामना करना मुर्खता है - यह पूरी तरह से गलत है। चुनौतियों से निपटने में साहस और समर्पण का प्रदर्शन व्यक्तिगत विकास, अनुभव और सिद्धांत का एक महत्वपूर्ण भाग होता है।

The correct solution is 'no error'.

Key Points

• While spotting an error in a given sentence, we have to check whether each part of the sentence is grammatically correct and whether the arrangement of the sentence is in correct order.
• In the sentence given above, the first section introduces us to the transcendence of God which is continued in the second section. The third part of the sentence explains the nature of the transcendence.
• Therefore the sentence does not contain any error.
• Hence, the correct answer is Option 3.

The correct solution is 'voltaic'. 

Key Points

• In the question above, the sentence is talking about 'power' which in this case means 'energy that is produced by mechanical, electrical, or other means and used to operate a device'.
• So, we have to find a word which has relation to this 'power' from the above options. 
• Option 1, 'voltaic' means "of, relating to, or producing direct electric current by chemical action (as in a battery)" and is therefore the correct option.
• Option 2, 'volatile' means "a substance easily evaporated at normal temperatures" and does not reflect what the sentence is trying to convey, so it is a wrong option.
• Option 3, 'verbose' means "using or expressed in more words than are need" and is used fir literary works and have no relation with 'power'.
• Option 4, 'venal' means "capable of being bought or obtained for money or other valuable consideration" and has no relation with the word 'power', so it is also a wrong option.
• Hence, the correct answer is option 1.

The correct solution is 'vulgarity'.

Key Points

• In the question given above, the first part of the sentence talks about something repulsive, something which arouse intense distaste.
• So we have to find a word which reflects this repulsiveness. 
• Option 1, 'veracity' cannot be the correct option because it means 'conformity with truth or fact' which have to relation with repulsiveness.
• Option 2, 'vexation' is not the right option because it means 'the state of being annoyed, frustrated, or worried" and cannot be used right after the word 'crude' which means 'coarse or explicit,'
• Option 3*, 'vulgarity'* is the correct option because it means 'coarse and rude' which explains perfectly what the first part of the sentence is trying to convey.
• Option 4, 'zeal' is again an incorrect option as it means ''great energy or enthusiasm' which has no relation to the sentence.
• Hence the correct answer is Option 3.

The correct solution is 'No error'.

Key Points

• In the sentence given above, it talks about a person eating more than one meal.
• A sentence does not usually begin with 'Hardly' but when it does, it is followed by an auxiliary verb. Even in the above sentence, the word 'hardly' is followed by the auxiliary verb 'was'.
• The second section of the sentence than continues to explain how the first meal was hardly finished and the third section talks about how the next meal was on his mind.
• Hence the correct answer is Option 4.

The correct solution is 'RPSQ'. 

Key Points

• While arranging jumbled up sentence, we have to arrange sentences, we have to carefully analyze the common point between them and  start rearranging them.
• In the question given above, we have the static portion of the sentence, 'The Gods in Greek mythology are very different from many modern ideas about religion'.
• We have to select a suitable phrase which comes after this static portion.
• Option R, 'They were seen as great powers and not as spiritual or benign figures, as in the Monotheistic religion' as this phrase started explaining the nature of the Greek Gods.
• Option P, 'Zeus became King of the Olympian gods, not because he was morally good or a creator god', comes next as this sentence explains the nature of the aforementioned Greek God Zeus.
• Option S, 'Instead, he came to power in a cosmic war', comes next as it explains the nature of Zeus.
• Option Q, 'He became the absolute ruler of the universe after overthrowing his father and by battling the Titans', would be the last as it defines the achievement of Zeus. '
• The sentence is concluded by the given static part of the question, 'Zeus became King the way that many other monarchs seized power, with brute force and cunning'.
• Hence, the correct answer is Option 1.

The correct solution is 'cripple'. 

Key Points

• The word given in the question 'disenable'  means 'deprive of the ability or capacity to do something'.
• Since, we have to find the synonym of the word, it would be Option 2, 'cripple' which means 'to deprive of capability for service or of strength, efficiency, or wholeness'
• Option 1, 'assuage' is not the correct option as it means 'make (an unpleasant feeling) less intense' which is not similar to the meaning is disenable.
• Option 3, 'assist' is a wrong answer because it means 'help (someone), typically by doing a share of the work' and is the antonym of the word disenable.
• Option 4, 'soothe' is also a wrong answer as it means 'reduce pain or discomfort in (a part of the body)'.
• Hence the correct answer is Option 2.

The correct solution is 'RQSP'. 

Key Points

• While arranging jumbled up sentences, we need to have a clear idea of what we are trying to convey and arrange the sentence accordingly.
• In the question above, the sentence begins with 'Two other species'. We have to pick the correct phrase which would come next.
• Option R. 'Of genus' and Option Q 'Myristica may'  would be the phrases to follow as it describes the nature of the 'two other species'.
• Option S 'Be used to' and Option P 'adulterate nutmeg' would follow as they finally described what the two other species are used for.
• Hence the correct answer is Option 3.

The correct solution is 'contencious'. 

Key Points

• Since we have to choose the incorrectly spelt word, the right answer is 'contentious- causing or likely to cause an argument; controversial**'.**
• The correctly spelt word would be 'contentious' which means 'causing or likely to cause an argument; controversial'.
• Option 1, 'quotidian' is a correctly spelt word which means 'of or occurring every day; daily.'
• Option 3, 'prevaricate' is a correctly spelt word which means ' to deviate from the truth'.
• Option 4, 'refute' is also a correctly spelt word which means 'prove (a statement or theory) to be wrong or false; disprove.'
• Hence the correct answer is option 2.

The correct solution is 'Having something that is certain is much better than taking a risk for more, because chances are you might losing everything'.

Key Points

• An idiom is a group of words established by usage as having a meaning not deducible from those of the individual words.
• The idiom given in the question 'A bird in the hand is worth two in the bush' is an idiom would means 'Having something that is certain is much better than taking a risk for more, because chances are you might losing everything'.
• The idiom for Option 1, 'A fair competition where no side has an advantage' would be 'level playing field'.
• The idiom for Option 3, 'Someone who is unpredictable and can cause damage if not kept in check' would be 'loose cannon'.
• The idiom for Option 4 'To state a fact so there are no doubts or objections' would be 'make no bones about it'
• Hence the correct answer is option 2.

The correct solution is 'immovable'. 

Key Points

• The word 'conveyable' given in the question means 'legally transferable to the ownership of another'.
• Since we have to find the word that is opposite in meaning, the correct answer would be 'immovable' which would mean ' incapable of being moved Or not transferable' 
• Option 2, 'ambulatory' means 'able to walk about and not bedridden' and is not opposite to the word 'conveyable'.
• Option 3, 'loose' means 'not firmly or tightly' and is more of a synonym rather than an antonym of the word 'conveyable'.
• Option 4, 'portal' means 'a doorway, gate, or other entrance, especially a large and imposing one' and is not related to the word conveyable.
• Hence the correct answer is Option 1.

The correct solution is 'His field ambulance had come under shellfire'. 

Key Points

• In the sentence given above, the bracketed part of the question 'His field ambulance had come from shellfire' is grammatically incorrect as the word 'from' indicates 'indicating the point in time at which a particular process, event, or activity starts'.
• The field ambulance cannot grammatically or physically come from a shellfire.
• The correct option would be option 4, 'His field ambulance had come under fire' is the correct answer as the word 'come under' means 'be subject to an influence or authority'.
• The sentence would mean that the Ambulance was influenced by the shellfire.
• Hence the correct answer is Option 4.

The correct solution is 'narrow minded'. 

Key Points

• An idiom is a group of words established by usage as having a meaning not deducible from those of the individual words.
• The meanings of the idioms given in the options are:
• Option 1, 'Jaywalk' is not an idiom and it means 'cross or walk in the street or road unlawfully or without regard for approaching traffic.' so it is not the correct option.
• Option 2, 'Go the extra mile' means 'to make a special effort to achieve something', and is also the wrong option.
• Option 3, 'Great minds think alike' is a humorous idiom used when 'someone just after you have discovered that they have had the same idea as you'. So this is also a wrong option.
• Option 4, 'Narrow minded' means 'not willing to listen to or tolerate other people's views; prejudiced' and is the correct option.
• Hence, the correct answer is Option 4.

The correct solution is 'propriety'. 

Key Points

• The word 'propriety' here means 'the quality or state of being proper or suitable OR conformity to what is socially acceptable in conduct or speech'.
• Option 2*,* 'proprety' has no meaning in English.
• Option 3, 'propreity' too is a misspelled form of propriety.
• Option 4, 'propariety' is also a meaningless word.
• Hence the correct answer is Option 1.

The correct solution is 'Anarchy'.

Key Points

• The expression given in the question is the definition of the word Anarchy.

• Option 3, 'Gazette' means 'a newspaper'
• Hence the correct option is Option 4.

The correct solution is "told us, "He would have been 16 if he were". 

Key Points

• The sentence given in the question is an direct speech in the form of present perfect tense.
• The present perfect tense is one of the common verb tenses in English, used to show an action that happened in the past that is directly related to the present, such as actions that are still continuing or that indicate a change over time.
• Option 1, 'told us, "He would have been 16 if he were' is the correct option because in a direct speech, we use the reporting verb 'told us' while 'reminded us' is used in the case of indirect speech.
• In the sentence given in the question, the auxiliary verb 'was' is also not correct because 'was is the first and third-person singular past tense of the verb to be, while were is the second-person singular past and plural past of to be' and in the given sentence the subject is referred to as a second person, so 'were' would be used instead.
• Hence the correct answer is Option 1.

The correct solution is 'Carbon dioxide'.

Key Points

• The answer to this question can be found from the first sentence itself, "Atoms of carbon, hydrogen and oxygen are put together to make molecules of sugar -a carbohydrate food substance".
• Here the sentence mentions that molecules of sugar are made up atom of carbon, hydrogen and oxygen. There is no mention of 'Carbon dioxide'.
• So the correct answer is Option 3.

The correct solution is 'through chlorophyll'. 

Key Points

• The answer to this question can be found on the sixth sentence, 'The light energy is trapped by a special chemical called chlorophyll'.
• Water is taken up through roots, air is taken through stomata and light is trapped by chlorophyll.
• Hence, the correct answer is Option 4.

The correct solution is 'Carbon dioxide is released at the end of photosynthesis'. 

Key Points

• In the question given above, we are asked to choose the 'incorrect' option and not the correct option.

The correct solution is 'Carbon- dioxide gas in the air'.

Key Points

• The answer to this question can be found on the first and the second sentence*, 'Atoms of carbon - hydrogen and oxygen are put together to make molecules of sugar -a carbohydrate food substance. The carbon comes from carbon dioxide gas in the air'.*
• From the first sentence we get to know that hydrogen and oxygen are atoms of carbon.
• From the second sentence, we get to know that this carbon comes from carbon dioxide gas in the air.
• Hence the correct answer is option 1.

The correct solution is 'Oxygen'. 

Key Points

• The answer to this question can be found in the last sentence ' The gas oxygen is left over at the end of photosynthesis and goes into the air'.
• From this sentence, we know that Oxygen that is left over at the end of photosynthesis and goes to air.
• Hence, the correct answer is Option 4.
