EPFO Assistant Previous Year Paper 1

The appropriate fit for the blank is ‘will have lost’ which is in the future perfect tense. The future perfect tense indicates that an action will be completed (finished or "perfected") at some point in the future. This tense’s format is: will+ have+ the past participle of the verb (which can be either regular or irregular in form)

The rest of the options are cancelled as their tenses are wrong.

Hence the correct answer is option 2.

NOTE: 

We use will:

• to talk about the future – to say what we believe will happen
• to talk about what people want to do or are willing to do
• to make promises and offers

would is the past tense form of will. Because it is a past tense it is used:

• to talk about the past.
• to talk about hypotheses – things that are imagined rather than true.
• for politeness.

The appropriate fit for the blank is ‘are leaving’ which is in present continuous tense. The present continuous tense is used for actions happening now or for an action that is unfinished. This tense is also used when the action is temporary. Another use of this tense is when we are talking about a planned event in the future.

The rest of the options are cancelled as the tenses are wrong.

Hence the correct answer is option 5.

The correct answer is option 2.

'Helping' is the present continuous tense of the verb 'help'. 

'Has helped' is the present perfect tense (has/have + past participle form of the verb)

'Will help' is the simple future tense(will/shall+verb).

'Help' is the simple present tense.

Since the sentence describes an action in the present which does not have a definite time, therefore, 'has helped' is the correct answer',

The correct answer is option 3.

'These days' is an adverb phrase used to denote an action that has been going on over a period of time, including the present.

'Was learning' is the past continuous tense (is/was+verb+ing).

'Learnt' is in the simple past tense.

'Am learning' is in the present continuous tense(am/are+verb+ing).

Given the sentence, which is in the present, 'am learning' is the correct answer.

The correct answer is 'Wake'

Key Points

• The sentence describes an action in a dramatic manner. This is called the 'historic present'. 
• 'Wake' is in the simple present form.
• 'Woke' is in the simple past form.
• 'Had woken' is in the past perfect form (had+past participle form of the verb).
• 'Will wake' is in the future simple form.

Since the sentence is in the 'historic present', therefore, simple present is the correct option.

The correct answer here is 'enable'.

Enable means 'to make a device or system operational'.

Able means 'to have the power, skill, means, or opportunity to do something'.

The other alternatives are grammatically incorrect, keeping in mind the tense of the sentence.

The sentence is framed in the present tense and the other alternatives are framed in the past tense and the present continuous tense respectively.

D is the correct answer.

'Deny' is the Present tense - it means that they reject or knowingly refuse to believe that the Holocaust happened.

Correct answer: 5.

The word has been used correctly in all the sentences. Hence, option 5 is the correct answer.

Correct answer: Option 4.

Sentence C does not make any sense contextually. We cannot push out of a valley. Hence, the word does not fit there.

Correct answer: 3.

Sentence C makes the mistake of using 'tired' instead of the correct word 'tried'.

It is mentioned in the passage: 

"And I have a magic mirror. If any woman who is not pure of heart or virtuous looks into my mirror, spots of her dishonest character will show in her reflection."

"Is looking into your mirror one of the conditions to marry the king?" asked all.

"That is the only condition," replied the barber.

Correct answer: Option 4.

Worthy means having or showing the qualities that deserve the specified action or regard.

The other words mean:

Nobel: Refers to the Noble Prize so cannot be a synonym.

Dire: extremely serious or urgent.

 

Brave: Courageous.

Hence, notable is the correct answer.

Correct answer: Option 1.

Shy means nervous or timid in the company of other people.

The other words mean:

Timid: Afraid.

Daring: Courageous.

Cultured: characterized by refined taste and manners and good education.

Hence, reserved which means slow to reveal emotion or opinions is the correct answer.

Correct answer: Option 2.

Glossy means something which is shiny.

The other words mean:

Eager: Showing enthusiasm to do something.

Dull: Something that is drab; uninspiring.

Shiny: Glossy.

Hence, dull is the correct answer.

Correct answer: Option 4.

The other words mean:

Generous: showing a readiness to give more of something, especially money, than is strictly necessary or expected.

Guiltless: having no guilt; innocent.

Sinful: wicked and immoral; committing or characterized by the committing of sins.

Correct answer: Option 1.

The answer to this question can be inferred from the following lines: "Everyone makes mistakes, and I am no different. I've made mistakes with my flock.  But they must forgive me because every day they let me take care of them all over again. With all due respect, Sire, I have no great desire to become queen.  But I am not afraid to look into that magic mirror."

She accepts the general truth that everybody makes mistakes and hence she learns from them.

Correct answer: 5.

The real reason why nobody dared to face the mirror can be inferred from what the king said at the end of the passage: But the king said, "No ladies, you have only yourselves to thank. If you had been as confident in yourself as this young lady, who is now going to be my queen, you too would not have been afraid to look into the mirror."

Correct answer: Option 5.

The answer to this question can be found in the following lines:

"Is looking into your mirror one of the conditions to marry the king?" asked all.

"That is the only condition," replied the barber.

Correct answer: Option 2.

The answer to the question can be inferred from this line: "Ah, Granada, Granada!" said the king. "Is there no maiden in this land who wants to be my bride?"

Correct answer: 5.

There is nothing mentioned in the passage regarding this topic.

Correct answer: Option 4.

The sentence does not support a verb in the place where 'weakened' is there. It wants a noun and hence the correct replacement is 'weekend'.

Correct option: 4.

The spelling of customar is wrong here.

The correct spelling is 'customer'.

Correct answer: Option 1.

The word 'tried' is incorrectly placed there. The sentence means that the horses were bounded by something and hence the correct word is 'tied'.

The correct answer is option 5.

All the words that are emboldened in the given sentence are correctly spelt and used in the sentence.

'Prescribe' means 'to advise and authorise the use of a medicine or treatment for someone, especially in writing'.

'Regimen' means 'a prescribed course of medical treatment, diet, or exercise for the promotion or restoration of health'.

'Ointment' means 'a smooth oily substance that is rubbed on the skin for medicinal purposes or as a cosmetic'.

Out of the given words, only perterbation is spelt incorrectly. Given the context, its correct spelling should be perturbation.

Evidently- in a way that is clearly seen or understood; obviously.

To divine- discover (something) by guesswork or intuition.

Perturbation- anxiety, mental uneasiness.

To hasten- be quick to do something.

Therefore, the correct answer is option 3.

The correct answer is 3.

To derive the fifth sentence of the correct arrangement, it is imperative to find out the first four sentences of the correct arrangement. From the above solution, we have been able to find out that the subject of the passage i.e. plastic waste management given by sentence C. Therefore, sentence C forms the first sentence. Taking the subject, i.e. plastic waste management further, the next question in order is the definition of plastic waste management. It is the use of discarded plastic materials without additional increase in plastic products. This issue has been taken up by sentence A. So sentence A forms the second sentence after rearrangement.

At this point, we know that the first two sentences of the correct arrangement would be CA.

The correct answer is 1.

Taking the subject, i.e. plastic waste management further, the next question in order is the definition of plastic waste management. It is the use of discarded plastic materials without additional increase in plastic products. This issue has been taken up by sentence A. So sentence A forms the second sentence after rearrangement.

Taking the passage’s subject further we come to know how plastic waste management would reduce contamination of the environment and how recycling used plastic materials would not create any more plastic products. This is given in sentence D. So sentence D forms the third sentence after rearrangement.

The correct answer is 4.

The next step in the passage is an example of how supermarkets encourage their customers to give unwanted plastics bags to them. This is taken up by sentence B making it the fifth sentence after rearrangement. At this point, we know that the first five sentences of the correct arrangement would be CADFB.

The correct answer is 2.

This is the concluding part of the passage which mentions the way in which used plastic materials are recycled in order to make new materials. This has been given by sentence E.

Therefore, the entire rearrangement order is, CADFBE.

The information given in represented as below,

Therefore, AC = AG + GB + BC = (4 + 4 + 6) km = 14 km.

The information given in represented as below,

 

Applying Pythagoras theorem,

(EF)² = (ED)² + (DF)² → (EF)² = (4)² + (3)² = 25

So, EF = 5 km

Thus distance between E and F is 5 km.

Given Series: 758      839      246      197      564

After interchanging first and third digits: 857      938      642      791      465

Here, 791 is the third largest number.

Hence, 197 is the correct answer.

Given Series: 758      839      246      197      564

Odd numbers: 839, 197

Even numbers: 758, 246, 564

On adding 1 to the first digit of odd numbers and 2 to the first digits of even numbers: 958      939      446      297      764​

Here, in 939 and 446 the digits are repeating more than once.

Hence, the answer is 'Two'.

Given Series: 758      839      246      197      564

After arranging in descending order from left to right: 839      758      564       246      197

Here, 564 is the third number from the right end.

Hence, the answer is 564.

Given Series: 758      839      246      197      564

On adding the digits:

758 → 7 + 5 + 8 = 20

839 → 8 + 3 + 9 = 20

246 → 2 + 4 + 6 = 12

197 → 1 + 9 + 7 = 17

564 → 5 + 6 + 4 = 15

12 is the lowest number after adding all digits of numbers.

Thus, 246 is the correct alternative.
