Important Points

Primary sector is the largest employer in India.  It employes about 64% of the Indian population. 
This sector produces only a quarter of GDP because in it, the first step of goods production takes place. It is the supplier of raw material to the secondary sector. And the value of the good increases on each subsequent step and primary sector provides the first step. So, it's share is quite less in GDP. 

The correct answer is '1920'.

Additional Information

वियोग शब्द 'वि' उपसर्ग से बना है।

• वि + योग = वियोग (वि उपसर्ग)
• 'वि' संस्कृत का उपसर्ग है।
• 'वि' उपसर्ग के उदाहरण - विवाद, विपक्ष, विशुद्ध।

Key Pointsअन्य विकल्प -

• विवाह + इक = वैवाहिक
• वीर मूल शब्द है।
• वीर + त्व = वीरक्त

Additional Informationउपसर्ग -

• उपसर्ग शब्द के शुरूआत में जुड़ते हैं और मूल शब्द का अर्थ बदल देते हैं।
• उदाहरण :- अप + यश = अपयश, अध + पका = अधपका, ना + लायक = नालायक, हाफ + टिकट = हाफटिकट आदि।
• हिन्दी में मुख्यतः चार प्रकार के उपसर्ग होते है :-
  • संस्कृत के उपसर्ग (प्र, परा, अप, सम्, अनु, अव, निस्, निर्, दुस्, दुर्, वि, आङ्, नि, अधि, अपि, अति, सु, उत्, अभि, प्रति, परि तथा उप)
  • हिंदी के उपसर्ग (अन, अध, उन, औ, कु, चौ, पच, पर, बिन, भर, स, सह, चिर, न, बहु, आप, सम, दु)
  • उर्दू के उपसर्ग (ला, बद, बे, कम, ग़ैर, ना, खुश, हम, ऐन, सर, बेश, बा, अल)
  • अंग्रेजी के उपसर्ग (ब, हाफ, को, हैड, वाइस)

• Identifying the missing word: We need to find the word that fits best in blank number 14 based on the context provided.


• Understanding the context: The sentence talks about ancestors punishing individuals who failed in their duty, indicating that those individuals were chastised by the ancestors.


• Analysis: The word "who" is the most appropriate choice for blank number 14 as it refers to individuals (people) who failed in their duty.


• Conclusion: Therefore, the correct answer is option A: who.

The sentence mentions that ancestors and dead relations punished people for both sins of commission and omission. Sins of commission refer to doing something that is wrong or forbidden, while sins of omission refer to not doing something that is required or expected. Therefore, the appropriate word for blank no. 12 is 'omission', as it refers to the failure to do something that should have been done, and is opposite to sins of commission.

• Identifying the Context: The sentence mentions an explanation that is heard in a certain situation.


• Understanding the Tone: The tone of the sentence suggests a pattern or frequency of occurrence.


• Considering the Options: Review the options provided to determine which one best fits the context and tone.

• Choice D: often - This word implies a frequent or regular recurrence, which aligns with the explanation being commonly heard in the context provided.

As we know that ,
Elan means vigor or energy and enthusiasm, opposite of enthusiasm would be nervousness, composure means calmness, dignity is calm and serious manner while brashness is opposite to composure.
Hence , Nervousness is opposite of ELAN . 

Gypsum acts as a retarder. It counteracts the fast rate of hydration (for which C₃A is primarily responsible) to prevent flash set.

Initial setting of Portland cement is due to the tricalcium aluminate. Tricalcium aluminate hydrates quickly, generates much heat and makes only small contribution to the strength within the first 24 hours. Among all the elements, the aluminate generates the maximum heat. Due to this, tricalcium aluminate is responsible for most of.the undesirable properties of concrete.

If v_s ≥ v_o, then there is 100% removal of particles and if v_s < v_o then there is 0% removal.

Average permeability parallel to the plane of stratification depends mainly on the permeability of the most permeable layer and its value is close to the permeability of that layer.

(c) In 2D incompressible and steady flow, pressure gradient in direction of flow is zero:

Sleeper density = n+4
and
sleeper density = 13+4=17
Thus, for 1000 m no of sleeper will be
= (17×1000)/13
= 1307.69=1308

Thixotropy is the property of a soil due to which the loss in shear strength caused by remoulding can be regained with the time.

Water logged area means where the irrigation of water is high. For construction in this area we use the cement mortar.
Cement mortar use to hold building materials such as brick or stone together. In this water to cement ratio is higher.

The SI unit of kinematic viscosity is square meters per second (m²/s).
Kinematic viscosity is a measure of a fluid's internal resistance to flow under gravitational forces. It is determined by measuring the time in seconds required for a fixed volume of fluid to flow a known distance by gravity through a capillary within a calibrated viscometer at a closely controlled temperature.
Hence, the correct option is (A).

given, dergee = 5
max. safe speed (Vmax) = 110km/hr
average speed(Vavg) = 85km/hr
For brouad gauge,
G= 1750 mm

= 486-284=192=19
But, max cant deficiency allowed (as per old IS code) is 10 cm.

Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness.

Durability of concrete depends on:
Cement content, Compaction, Curing, Cover, Permeability

Contour interpolation is an operation that first rasterizes contour lines of a segment map with a value domain and then calculates values for pixels that are not covered by segments by means of linear interpolation. Furthermore, on the command line, this operation can also use an input raster map.

Hence, the correct option is (C).
