According to the given information, the possible diagram is:

From the above diagram, the Shortest distance between Ashok and Vivek is = 5 + 4 = 9 km

Hence, the correct answer is "9 km".

According to the given information, the logic followed here is:

7, 4, 2, 69

7² + 4² + 2²

= 49 +16 + 4

= 65 + 4

= 69

3, 9, 1, 91

3² + 9² + 1²

= 9 + 81 + 1

= 90 + 1

= 91

2, 6, 5, ?

2² + 6² + 5²

= 4 + 36 + 25

= 40 + 25

= 65

Hence, the correct answer is "65".

The logic followed here is:

Word is coded according to the place value of each letter in that word,

Similarly, the code for "BABY" is,

Hence, the correct answer is "21225".

The logic followed here is:

Hence, the odd one out is "PQS".

The correct solution is Radon.

Key Points

• In the Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, 0.9 % argon, and 0.1 % other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 %.
• Trace amounts of neon, helium, methane, krypton, and hydrogen, as well as water vapor.

The correct answer is Regur Soil.

Key Points

• Black Soils are commonly referred to as regur but are widely known as “black cotton soils,” as cotton has been the most common conventional crop in areas where they are found.
• This type of soil is typical found in the Deccan Trap (Basalt) region which spreads over northwest Deccan plateau and is made from lava flows.
• The Black soil or Regur is found on the plateaus of Maharashtra, Saurashtra, Malwa, Madhya Pradesh, Chhattisgarh and stretch in the Southeast direction along the Godavari and the Krishna Valleys.
• The properties of such soils include the following: high compressibility, low bearing capacity, and low shearing strength.
• The Black soils are made up of clayey materials and are widely known for their capacity to hold moisture.
• The Black soils are highly prosperous in calcium carbonate, magnesium, potash, and lime.

The correct answer is Maski.

Key Points

• The Edicts of Ashoka are a collection of more than thirty inscriptions on the pillars, as well as boulders and cave walls, attributed to Emperor Ashoka of the Mauryan Empire who reigned from 268 BCE to 232 BCE.

The correct answer is Delta.

• There are three types of particles i.e Alpha, Beta and Gamma.
• Alpha - Deflected towards the negative plate
• Beta - Deflected towards the positive plate
• Gamma - No deflection is shown towards any plate.

Additional Information

• Alpha Radioactive decay:
• α-decay is a type of radioactive decay.
• In this, an atomic nucleus emits an alpha particle i.e helium nucleus and another element with energy.
• It decreases the atomic number by 2 and atomic mass by 4.
• Beta Radioactive Decay:
• The nucleus decays spontaneously by emitting an electron or a positron.
• eg. 3215P → 3216S + e– + v–
• In this decay atomic number of product, elements increase by one.
• Gamma radioactive decay:
• In this, no change in atomic no or atomic mass is there.
• A* → A + γ
• A* is the excited atom.
• A  is a relaxed state of the initially excited atom.
