एक त्रिकोण की भुजाएँ 3: 4: 6 के अनुपात में हैं। त्रिकोण किस प्रकार का है:
a)
तीव्र कोण वाला
b)
समकोण वाला
c)
उबड़-खाबड़ कोण वाला
d)
या तो तीव्र कोण वाला या समकोण वाला
Correct answer is option 'C'. Can you explain this answer?

Spectrum Coaching Institute answered

मान लेते हैं कि त्रिकोण की भुजाएँ 3x, 4x और 6x इकाई हैं।
स्पष्ट रूप से, (3x)² + (4x)² < (6x)²
अत: त्रिकोण उबड़-खाबड़ कोण वाला होगा।
इसलिए, विकल्प C सही है।

एक चक्रीय चतुर्भुज ABCD ऐसा है कि AB = BC, AD = DC, AC ⊥ BD। ∠CAD = Θ। तब कोण ∠ABC =
a)
Θ
b)
c)
2Θ
d)
3Θ
Correct answer is option 'C'. Can you explain this answer?

Target Study Academy answered

त्रिभुज ABC में,
दी गई जानकारी: AB = BC
∠BCA = ∠BAC
और, AD = DC
∠CAD = ∠ACD
इसलिए ∠DAB = ∠DCB
इसलिए ∠DAB + ∠DCB = 180° ⇒ 2∠DAB = 180°
इसलिए ∠DAB = 90° = ∠DCB
त्रिभुज ADE में, हमें पता है कि

इसलिए ∠ADE = 180° – 90° – Θ = 90° – Θ
इसलिए ∠ADC = ∠ADE + ∠CDE = 2(90° – Θ)
∠ABC + ∠ADC = 180°
∠ABC = 180° – ∠ADC = 180° – 2(90° – Θ) = 2Θ
इसलिए, विकल्प C सही है।

What percentage of NDPS cases in Kerala are related to possession rather than trafficking?
a)
6%
b)
94%
c)
50%
d)
75%
Correct answer is option 'B'. Can you explain this answer?

Wizius Careers answered

In Kerala, a staggering 94% of NDPS cases pertain to possession, indicating a significant focus on consumers rather than traffickers. This imbalance suggests that law enforcement is primarily addressing the end users of drugs, which may detract from efforts to combat trafficking networks. Understanding this disparity is crucial for developing targeted strategies to address the drug crisis effectively. Interestingly, this situation reflects a broader trend seen in various regions, where the enforcement focus often leans more towards users than suppliers, complicating the fight against drug abuse.

What is one significant challenge faced in the implementation of gender-centric welfare schemes for marginalized women?
a)
Increased funding allocations
b)
Universal digital literacy among beneficiaries
c)
Bureaucratic delays in fund disbursement
d)
High levels of community involvement
Correct answer is option 'C'. Can you explain this answer?

Iq Funda answered

Bureaucratic delays in fund disbursement present a major challenge in implementing gender-centric welfare schemes. Lengthy approval processes and administrative hurdles can hinder timely access to funds, which diminishes the effectiveness of programs intended to support marginalized women. For instance, delays in disbursing scholarships to SC/ST students illustrate how administrative inefficiencies can obstruct the delivery of essential services. This highlights the need for streamlined processes to ensure that intended beneficiaries receive the support they need in a timely manner. An additional fact is that improving bureaucratic efficiency can significantly enhance the impact of welfare initiatives, thereby benefiting the communities they aim to serve.

1. Large Phased Array Radar (LPAR) - China: This pair is correctly matched. China has deployed a sophisticated Large Phased Array Radar in Yunnan province, enhancing its surveillance capabilities.

2. Stockholm International Peace Research Institute (SIPRI) - Geneva: This pair is incorrectly matched. The Stockholm International Peace Research Institute (SIPRI) is located in Stockholm, Sweden, not Geneva.

3. KHANJAR-XII Exercise - India and Kyrgyzstan: This pair is correctly matched. The KHANJAR-XII is a joint military exercise between India and Kyrgyzstan, focusing on counterterrorism and special forces operations.

4. PAVE PAWS Radar - United Kingdom: This pair is incorrectly matched. The PAVE PAWS radar is a United States radar system, not related to the United Kingdom.

Pairs 1 and 3 are correctly matched, while pairs 2 and 4 are incorrectly matched. Thus, there are two correctly matched pairs.

a)

b)
hillock
c)
plain surface
d)
None of the above
Correct answer is option 'B'. Can you explain this answer?

Gate Funda answered

Closed contours with higher values inwards represent a depression.

Explanation:

Depression: In topographic maps, a depression is shown by closed contours with the highest elevation in the center. These contours are typically marked with hachure lines (short lines) pointing towards the center of the depression to indicate that the terrain dips downward.
Hillock: A hillock would have the highest elevation at the center, with contours arranged around it in concentric circles, representing a rise in elevation, not a depression.
Plain Surface: A plain would be represented by evenly spaced, straight, or gently curved contours, showing a flat or nearly level surface.

Fly ash is added to concrete to improve all of the following properties EXCEPT:
a)
Permeability
b)
Workability
c)
Long term strength
d)
Early age strength gain
Correct answer is option 'D'. Can you explain this answer?

Akshat Datta answered

The use of fly ash in portland cement concrete (PCC) has many benefits and improves concrete performance in both the fresh and hardened state. Generally, fly ash benefits fresh concrete by reducing the mixing water requirement and improving the paste flow behavior.

Fly ash benefits to fresh concrete are:

1. Improved workability: The spherical shaped particles of fly ash act as miniature ball bearings within the concrete mix, thus providing a lubricant effect. This same effect also improves concrete pumpability by reducing frictional losses during the pumping process and flat work finishability.
