- The HL-2M Tokamak reactor is China’s largest and most advanced nuclear fusion experimental research device, and scientists hope that the device can potentially unlock a powerful clean energy source.
- It uses a powerful magnetic field to fuse hot plasma and can reach temperatures of over 150 million degrees Celsius, according to the People’s Daily — approximately ten times hotter than the core of the sun.
- Located in Sichuan province and completed late last year, the reactor is often called an “artificial sun” on account of the enormous heat and power it produces.
- They plan to use the device in collaboration with scientists working on the International Thermonuclear Experimental Reactor (ITER) — the world’s largest nuclear fusion research project based in France, which is expected to be completed in 2025.

Important Point

Fusion Reaction is what powers our sun :
- It merges atomic nuclei to create massive amounts of energy—the opposite of the fission process used in atomic weapons and nuclear power plants, which splits them into fragments.
- Unlike fission, fusion does not create radioactive waste and carries less risk of accidents or the theft of atomic material.
- But achieving fusion is both extremely difficult and prohibitively expensive, with the total cost of ITER estimated at $22.5 billion.

Speed in upstream = 40 – 40/2 = 20 km/h

Required time = 60/20 = 3 hrs

26. A & B working alone 9 hours a day can complete a job in 14 days and 12 days respectively. In how many would they finish the job if they work together 6 hours per day?

A. 126/13

B. 88/13

C. 111/13

D. 10

Solutions

Short Trick:

A takes 14 days working 9 hours a day, if he works 6 hours a day he will take

14*9/6 = 21 days

B takes 12 days working 9 hours a day, if he works 6 hours a day he will take

12*9/6 = 18 days

D — W — E

A 21 — 126 — 6

B 18 — 126 — 7

Time taken by A+B together in doing 126 work

= 126/13 days

Basic Method:

⇒126 A = 108 B = W, where W is the quantum of work in work units

⇒If working together 9 hours a day they finish the job in d days,

⇒ 6d (A + B) = W

⇒From the given conditions,

A = W/126 & B = W/108

⇒So when working together,

6d (A + B) = W

6d (W/126 + W/108) = W

⇒ 6d (1/126 + 1/108) = 1

⇒13/126 = 1/d

⇒∴d = 126/13 days

29. Anand marks up the price of an article by 50% and then allows a discount of 20% and sells it to Balaji. Balaji sells it for Rs.20 more than what he purchased for this S.P is 30% more than the original C.P of the article. Then Balaji’s profit % is

A. 7.5%

B. 6.66%

C. 8.33%

D. 9%

Solutions

Short Trick:

CP = 100

MP = 150

Balaji’s CP = 150 – 30 =120

Balaji’s SP = 100 + 30 =130

Balaji’s profit = 10*100/120 = 25/3 %

Basic Method:

Let C. P. = x

Anand Mark up this price by 50% hence new price = x+ 50% of x

Hence the price in which Anand sold the article to Balaji =

Balaji sell the same article for Rs.20 more than what he purchased

This price is 30% more than the original C. P. (x)

Hence

Hence Balaji’s profit = Balaji’s C.P. – Balaji’s S. P. = 20

% profit of Balaji = Profit×100 / C. P. of Balaji

30. How many numbers from 33 to 143 are divisible by both 4 and 7?

Total profit earned = Rs. 38.40 + Rs. 115.20 = Rs. 153.60

Alternative approach:

Using alligation :

10 20
x
20-x x-10

Now (20-x)/(x-10) = 8/12 = 2/3

5x = 80

x= 16%

B. 11.97 m/s

C. 13.63 m/s

D. 16.50 m/s

Solutions

Speed of A = 63 × 5/18 = 17.5 m/s

Let the length of train A is L meters and the speed of train B is v km/h.

Relative speed for opposite direction = (17.5+v) m/s

Relative speed for same direction = (17.5-v) m/s

Now adding, (i) + (ii)

34. 2 boys and 3 men earn Rs 1000 in 5 days. 3 boys and 2 men earn Rs 600 in 4 days. In what time will 3 men and 2 boys earn Rs 2000?

A. 14 days

B. 15 days

C. 12 days

D. 10 days

Solutions

Let 1 man earn be m Rs/day

Let 1 boy earn be b Rs/day

According to the question

5(2b+3m) = 1000

2b + 3m = 200………………….(eq.1)

And 4(3b+2m) =600

3b+2m = 150………………….(eq.2)

Now, (3*eq.1)-(2*eq.2):

=>9m-4m =600-300

=>m = 300/5 =60

=>m = Rs 60 per day and b = Rs 10 per day

Now, 3m+4b = 3*60+2*10 = Rs 200 per day

And 3m+4b earn Rs 2000 for x days

So, x= 2000/200= 10 days

35. The difference in compound interest on a certain sum at 10% p.a. for one year, when the interest is compounded half yearly and yearly, is Rs. 88.80. What is the simple interest on the same sum for years at the same rate?

A. Rs. 5,920

B. Rs. 5,980

C. Rs. 5,986

D. Rs. 5,916

Solutions

Let the sum = 100 units

Case-1:

Rate = 10% p.a. compounded yearly

Time = 1 year

C.I. = P(1 + r/100)^t – P

C.I. = 100(1 + 10/100)¹ – 100 = 10 units

Case-2:

Rate = 10% p.a. compounded half yearly

Time = 1 year

C.I. = P[1 + (rate/2)/100]^(2×time) – P = 100(1 + 5/100)² – 100

= 110.25 – 100 = 10.25 units

A.T.Q.:

⇒ 10.25 – 10 = 0.25 units = Rs. 88.80

⇒ 100 unit = Rs. 35520

Hence, sum = Rs. 35,520

Now we will find simple interest on the same sum for years at the same rate.

A. 2 : 1

B. 1 : 2

C. 1 : 4

D. 4 : 1

Solutions

Let, the third proportion of 12 and 6√5 is x.

If 12, 6√5 and x will be in continuous proportion.

Then, 12/(6√5) = (6√5)/x

⇒ 12x = 6√5 × 6√5

= 12x = 36 × 5

⇒ x = 15

Mean proportional between 24 and 150 =

∴ Required ratio = 60 : 15 = 4 : 1

A. 5

B. 7

C. 11

D. 15

Solutions

Sum of ‘n’ natural numbers is given by:

{n × (n + 1)} / 2

Therefore, sum of first 20 natural numbers will be:

{20 × (20 + 1)} / 2

(20 × 21) / 2

420 / 2

210

And, the given sum is: 215

Now the number which has been added twice is: 215 – 210 = 5

Hence, the correct option is A

70. Choose an incorrect/ incomplete sentence:

A. We all felt like we ate too much.

B. Brad came to dinner with us.

C. Clean out the fridge before go.

D. There is so much to understand.

Solutions

Option C has an incomplete/incorrect sentence. The sentence has two parts: one dependent (before go) and one independent clause (clean out the fridge). The dependent clause doesn’t have the subject for the verb ‘go’. Thus, add the subject ‘you’ before the verb or make it a gerund i.e. “going” to make the sentence grammatically correct.

71. Among the two statements:

I. No sooner had I walked in the door then the phone rang.

II. Never she read such a sad book as The Coldest Tear.

A. Both are correct.

B. (I) is correct, (II) is incorrect.

C. (I) is incorrect, (II) is correct.

D. Both are incorrect.

Solutions

Sentence (I) and sentence (II) are grammatically incorrect. Sentence (I) contains correlative conjunction i.e. “no sooner….than” which is used for saying that something happens immediately after something else. Thus, replace ‘then’ (can be used as a noun, adjective, or adverb) with “than” to make the sentence grammatically correct.

Sentence (II) starts with a negative adverb ‘never’. When a sentence starts with a negative adverb, we use ‘inversion’, i.e. we use the verb before the subject. Thus, change the sentence (II) as: Never had she read such a sad book as The Coldest Tear.

A. I love to bake a cake.

B. The work its is easy.

C. Would you mind the gap?

D. None of above.

Solutions

Option B has a sentence that has an incorrect form of words. The use of the pronoun ‘its’ is erroneous and it should be replaced with ‘itself’. “Itself” is the reflexive pronoun of it, as in “History repeats itself”. “Its” is a possessive pronoun. Here, we need a reflexive pronoun, it is used when the subject and the object of a sentence are the same. Thus, replace ‘its’ with ‘itself’ to make the sentence grammatically sound.

75. It is newspaper that _____ us news.

A. give

B. is giving

C. gives

D. has given

Solutions

The sentence is of simple present tense and the subject “newspaper” is singular. Therefore, the verb should also be singular and of simple present tense. Going by this, we can say that the correct verb is “gives”.

76. Which sentence from the following is correct?

A. What did you want I to say?

B. The children ride often their bikes.

C. The data has been fed into the computer.

D. I thought the movie ended abrupt.

Solutions

Option C has the correct sentence.

Option A: is incorrect because there is a need for objective case not the nominative case; thus use “me” in place of “I”.

Option B: is incorrect because the adverb ‘often’ has been incorrectly placed. It should be placed before ‘ride’.

Option C: is grammatically correct.

NOTE- The word ‘data’ is a plural noun but here ‘the data’ denotes the particular set of information, thus, ‘is’, is correctly placed here.

Option D: is incorrect because the verb ‘ended’ will be modified by an adverb ‘abruptly’.

77. Identify the incorrect pair.

A. Calumny : Defamation

B. Endeavour : Aspire
