DSSSB Junior Clerk Mock Test - 6 - DSSSB TGT/PGT/PRT MCQ

The correct answer is Accept electrons.

Concept-:

Oxidation number-

• It is the number of charges which remain on an atom if all the bonds on the compound is assumed to be ionic bonds.
• Oxidation numbers can be negative, positive, or zero.

Oxidation:

• It is the process of loss of one or more electrons by atoms or ions.
• It can also be said as the combination of oxygen with another element.
• Removal of hydrogen from chemical compounds.
• Example-Mg + O₂ = Mg₂O.

Explanation:

Reduction:

• In the process of reduction, a chemical species gains electrons.
• There is an increase in the total negative charge on that atom.

Oxidizing agents.

• An oxidizing agent is one that gains electrons and is then reduced to a lower oxidation state.
• In the process of oxidation, there is the loss of electrons by atoms or ions.
• The lost electrons get transferred to some other substance and that substance is reduced.
• These substances are the oxidizing agents.

Thus, an oxidizing agent is a substance that can accept electrons.

The correct answer is an Excise tax.

• Tax can be divided into two categories.
• Excise Tax: Excise taxes can be used to price an externality or discourage consumption of a product that imposes costs on others.
• They can also be employed as a user fee to generate revenue from people who use particular government services, revenue which should be used to maintain that government service.
• At the moment, excise duty is charged at 12.36% but it varies based on the kind of products.
• Goods and Service Tax, on the other hand, has standard rates at 0%, 5%, 12%, 18%, and 28% depending upon the kind of product.
• GST has now subsumed a number of indirect taxes including excise duty.
• This means excise duty, technically, does not exist in India except on a few items such as liquor and petroleum.

Key Points

• First is Direct Tax such as Income tax, wealth tax, and corporation tax.
• The second is Indirect Tax such as Sales tax, Excise duty, and customs duty.
• Indirect tax means that tax that reaches the government indirectly.
• Such tax is completely opposite to direct tax.
• The tax levied by the state on consumption, import, export, production, etc. is an indirect tax.
• Excise Duty is a type of Indirect Tax which is imposed on all production or manufacturing of goods.

The correct answer is Mir Qasim

• In 1763, there was a war between the English and Mir Kasim, after being defeated, Mir Kasim went to the shelter of Shujauddaula, the Nawab of Awadh.

  • Shah Alam II, the Mughal Emperor.
• Both the Nawabs were governors under the Mughal Emperor.
• This historic battle was fought on 23rd October 1764.

Key Points

• The battle was fought at a place called Buxar, which was in Bengal during that time, and later on, it became a part of Bihar, as it was just 130 km west of Patna.
• The historic battle fought between the British and the Indian forces resulted in a victory for the British.
• The three combined army forces of Mir Qasim (Bengal), Shuja-ud-Daulah (Awadh), and Mughal Emperor Shah Alam II met with a crushing defeat under the hands of Major Munro.
• After the war, Mir Kasim fled to the North-West and died. Shah Alam II left Shuja-ud-Daulah and sought shelter in the British camp. Shuja-ud-Daulah tried to defeat the British till 1765 but was not successful. He later fled to Rohilkhand.

A season is a part of a year. A year is usually divided into summer, winter, spring, and autumn seasons.

Important Points

Seasons change due to the change in the position of the earth around the sun. ​

• The movement of the earth around the sun in a fixed path or orbit is called Revolution.
• It takes 365 days i.e. one year to revolve around the sun.
• The hemisphere receiving the most direct sunlight experiences spring and summer, while the other experiences autumn and winter.
• During the warmer months, the Sun is higher in the sky, stays above the horizon for longer, and its rays are more direct.
• During the cooler half, the Sun’s rays aren’t as strong and it’s lower in the sky.

Thus, it is clear that the change of the seasons is caused due to Revolution. and tilt of the earth in its axis.

From the given information,

1) Rohan was ranked lower than Sanju.

Rohan < Sanju

2) Vishal was ranked just higher than Disha.

Vishal > Disha

3) Kiran’s rank was between Rohan and Vishal.

Case 1: Rohan > Kiran > Vishal

Case 2: Vishal > Kiran > Rohan

According to statements 1) and 2), eliminate case 2.

Sanju > Rohan > Kiran > Vishal > Disha.

Hence, Sanju is the highest rank.

By decoding given information :

324 ÷ 36 × 7 + 34 - 28

Using BODMAS rule,

= 9 × 7 + 34 - 28

= 63 + 6

= 69

Hence, '69' is the correct answer

Calculation:
According to the question,
Total sales of branches B1, B3 and B5 together for both the years (in thousand numbers)
⇒ Total sales of branch B1 for both years + Total sales of branch B3 for both years + Total sales of branch B5 for both
years
⇒ (80 + 105) + (95 + 110) + (75 + 95)
⇒ 185 + 205 + 170
⇒ 560
∴ The total sales of branches B1, B3 and B5 together for both the years (in thousand numbers) is 560.

Given:

20% of his monthly salary on food

25% of rest on the education

30% of the rest on other expenditure

Amount left = Rs. 6,300

Calculation:

Let the total monthly salary be x

According to the question

⇒ (x) × (80/100) × (75/100) × (70/100) = 6300

⇒ (x) × (4/5) × (3/4) × (7/10) = 6300

⇒ x = (6300 × 200)/84

⇒ x = Rs. 15,000

∴ The total monthly salary is Rs. 15,000.

Let the length of the train be 2x km

⇒ Length of platform = (1/2) × 2x = x km

As train crosses a platform half of its length with a speed of 72 km/hr in 1 minute,

⇒ Speed = 72 km/hr = 72 × (5/18) = 20 m/sec

⇒ Time = 1 minute = 60 second

Now,

⇒ Distance = speed × time

⇒ x + 2x = 20 × 60

⇒ 3x = 1200

⇒ x = 400 m

Now,

⇒ Length of another train = 2 × 2x = 4x = 4 × 400 = 1600 m

⇒ Speed = 60% of 20 = 12 m/sec

⇒ Time in crossing another train = distance/speed = (1600 + 800)/12 = 2400/12 = 200 seconds

Given:

Two equations are:

(x2 - 4x + 10 + p) ----(i)

(x2 + 3x - q + 16) ----(ii)

HCF = (x -1)

Concept used:

If an equation, ax² + bx + c has HCF = x - a

Then we put x = a in the given equation ax2 + bx + c and check if it is equal to 0

Calculations:

Putting the value of x = 1 in equation (i),

⇒ (1)2 - 4 × (1) + 10 + p = 0

⇒ 1 - 4 + 10 + p = 0

⇒ p = -7

Putting the value of x = 1 in equation (ii),

⇒ (1)2 + 3 × (1) - q + 16 = 0

⇒ 1 + 3 - q + 16 = 0

⇒ q = 20

Putting the value of p and q, we get

⇒ p2 + q2 = (-7)2 + 202

⇒ 49 + 400

⇒ 449

∴ The value of p2 + q2 is 449

Given:

Distance = 28 km

Upstream time = 4 hr 40 min = 4 (2/3) hr = 14/3 hr

Downstream time = 2 hr

Formula used:

Speed = distance/time

Calculation:

Suppose, the speed of the boat in still water is x km/hr and the speed of current is y km/hr.

⇒ Upstream speed, x - y = 28/(14/3)

⇒ x - y = 6 ---- (1)

Downstream speed, x + y = 28/2

⇒ x + y = 14 ---- (2)

Add both the equation -

⇒ 2x = (6 + 14)

⇒ x = 20/2

⇒ x = 10 km/hr

∴ the speed of the boat in the still water = 10 km/hr.

Given:

Total car sold in the month = 25,000

Calculation:

From the given Pie chart,

Car sold by company E = 15%

Number of Car sold by company E ⇒ 25,000 × 15/100

= 3,750

∴ The number of cars sold by company E is 3750.

स्पष्टीकरण

इसका सही उत्तर विकल्प 2 'जिसका भाव सुनते ही श्रोता की समझ में आ जाये​' है। अन्य विकल्प सही उत्तर नहीं हैं।

• लेखक के अनुसार किस काव्य में प्रसाद गुण होता है - जिसका भाव सुनते ही श्रोता की समझ में आ जाये।
• सन्दर्भ पंक्ति - जिस तरह पके हुए अंगूर का रस बाहर से झलकता है, उसी तरह प्रसाद गुण परिप्लुत कविता का भावार्थ शब्दों के भीतर से झलकता है। उसके हृदयंगम होने में देर नहीं लगती। अतएव, जिस काव्य में करुणार्द्र संदेश और प्रेमातिशय द्योतक बातें हों, उस में प्रसाद गुण की कितनी आवश्यकता है, यह सहृदय जनों को बताना न पड़ेगा।

महत्वपूर्ण बिंदु

काव्य गुण - जिस प्रकार मनुष्य के शरीर में शूरवीरता, सच्चरित्रता, उदारता, करुणा, परोपकार आदि मानवीय गुण होते हैं, ठीक उसी प्रकार काव्य में भी प्रसाद, ओज, माधुर्य आदि गुण होते हैं। अतएव जैसे चारित्रिक गणों के कारण मनुष्य की शोभा बढ़ती है वैसे ही काव्य में भी इन गुणों का संचार होने से उसके आत्मतत्त्व या रस में दिव्य चमक सी आ जाती है।

यह मुख्य रूप से तीन होते हैं -

1. प्रसाद गुण: ऐसी काव्य रचना जिसको पढ़ते ही अर्थ ग्रहण हो जाता है, वह प्रसाद गुण से युक्त मानी जाती है। अर्थात् जब बिना किसी विशेष प्रयास के काव्य का अर्थ स्वतः ही स्पष्ट हो जाता है, उसे प्रसाद गुण युक्त काव्य कहते हैं।

2. ओज गुण: ऐसी काव्य रचना जिसको पढ़ने से चित्त में जोश, वीरता, उल्लास आदि की भावना उत्पन्न हो जाती है, वह ओज गुण युक्त काव्य रचना मानी जाती है।

3. माधुर्य गुण: हृदय को आनन्द उल्लास से द्रवित करने वाली कोमल कांत पदावली से युक्त रचना माधुर्य गुण सम्पन्न होती है। अर्थात् ऐसी काव्य रचना जिसको पढ़कर चित्त में श्रृंगार, करुणा या शांति के भाव उत्पन्न होते हैं, वह माधुर्य गुण युक्त रचना मानी जाती है।

इसका सही उत्तर विकल्प 4 'इसमें दीनता और भक्ति की प्रधानता है' है। अन्य विकल्प सही उत्तर नहीं हैं।

• कालिदास की कृति 'मेघदूत' के संबंध में सही कथन नहीं है- प्रसाद गुण इसमें दीनता और भक्ति की प्रधानता है।
• सन्दर्भ पंक्ति - यही समझकर महाकवि कालिदास ने 'मेघदूत' को प्रसाद गुण से ओत-प्रोत कर दिया है। यही सोचकर उन्होंने इस काव्य की रचना वैदर्भी रीति में की है- चुन-चुनकर सरल और कोमल शब्द रखे हैं; लम्बे-लम्बे समासों को पास तक नहीं फटकने दिया।

महत्वपूर्ण बिंदु

काव्य गुण - जिस प्रकार मनुष्य के शरीर में शूरवीरता, सच्चरित्रता, उदारता, करुणा, परोपकार आदि मानवीय गुण होते हैं, ठीक उसी प्रकार काव्य में भी प्रसाद, ओज, माधुर्य आदि गुण होते हैं। अतएव जैसे चारित्रिक गणों के कारण मनुष्य की शोभा बढ़ती है वैसे ही काव्य में भी इन गुणों का संचार होने से उसके आत्मतत्त्व या रस में दिव्य चमक सी आ जाती है।
