Let monthly salary of Veer be M.

Veer spends 15% of his monthly income on the house rent,

⇒ Amount on House rent = 15M/100 = 3M/20

⇒ Rest = M – 3M/20 = 17M/20

60% of the rest on household expenditure,

⇒ Amount on Household expenditure = 60/100 × 17M/20 = 51M/100

⇒ Rest = 17M/20 – 51M/100 = 34M/100

he saves Rs. 2210,

⇒ 34M/100 = 2210

⇒ M = 6500

∴ Veer's monthly salary is Rs. 6500

The pattern followed here is:

Similarly,

Hence, ‘FBESUM’ is the correct answer.

The correct answer is Mahanadi - Godavari - Krishna - Kaveri.

The correct answer is Leprosy.

Key Points

• Leprosy, also known as Hansen's disease (HD).
  • It is a chronic bacterial disease.
  • Leprosy produces skin ulcers, nerve damage, and muscle weakness.

Additional Information

• ​Chikungunya -

  • The virus of this disease is an arbovirus which is believed to belong to the alphavirus family.​
• Diabetes -
  • It is a group of metabolic diseases.
  • This disease occurs due to high blood sugar levels or insufficient insulin production in the person.
  • In this disease, the cells of the body are not able to produce insulin properly or react to the production of insulin.​
• Fluorosis -
  • This disease occurs due to excessive entry of fluoride or hydrofluoric acid into the body.
  • Fluoride is an element found in soil or water.
  • Which usually enters the body through drinking water or food.

CALCULATION:

x + 50y = 120

⇒ x + 50(x / 10) = 120

⇒ x + 5x = 120

⇒ x = 120 / 6 = 20

Now,

y = 20 / 10 = 2

∴ x = 20 and y = 2

The logic followed here is:

Therefore, the next term is "644".

Hence, the correct answer is "option (1)".

Short Trick:

Total work = 40/2 × 3 = 60

Time taken by Surya and Ramya when they work together

= 60/4 = 15 days

Detailed Solution:

Efficiency ratio of Surya to Ramya = 3 : 1

⇒ Ratio of time taken by Surya and Ramya = 1 : 3 (∵ time α 1/efficiency)

Let the time taken by Surya to complete the work alone be 'x' days and Ramya to complete the work alone be '3x' days.

Given, 3x - x = 40

⇒ 2x = 40

⇒ x = 20

⇒ Time taken by Surya to complete the work alone = 20 days

⇒ Time taken by Ramya to complete the work alone = 60 days

⇒ Total work = Efficiency × No. of days

⇒ Total work = 3 × 20 = 60 units

⇒ One day work Surya = 3 units

⇒ One day work of Ramya = 1 units

∴ When they work together, time taken to complete the work = 60/4 = 15 days

The logic followed here is :-

Hydrophobia means extreme or irrational fear of water.

Similarly,

Acrophobia means extreme or irrational fear of heights.

Hence, the correct answer is "Height".

The Correct Answer is Option (3) i.e Concave Mirror.

CONCEPT:

• Spherical mirrors are of two types - Convex mirror, and Concave mirror.
  • The image formed by the spherical mirrors depends on the position of the object.

• Convex mirror: If the outer surface of the spherical mirror is the reflecting surface then it is called a convex mirror. It is also called the diverging mirror.
  • The nature of the image formed by a convex mirror does not depend on the distance of the object from the mirror. These images are always virtual, smaller than the object, and situated behind the mirror.
• Concave mirror: If the inner surface of the spherical mirror is the reflecting surface, then it is called a concave mirror. It is also called a focusing mirror/converging mirror.
  • The size of the image produced by these mirrors can be larger or smaller than the object, depending upon the distance of the object from the mirror.
  • The concave mirror can form both real as well as virtual images of any object.
• Plane mirrors are the most commonly used mirrors. Lateral inversion is seen in the plane mirror.

EXPLANATION:

• The convex mirror always forms a virtual image that lies between pole and focus of the mirror. A virtual image is always erect.
• The convex mirror always forms the image which is smaller than the size of the object.

• The concave mirror can form enlarged as well as smaller images. So option 1 is correct.
• The plane mirror always forms the image of the same size as that of the object.

Important Point

The correct answer is Only two.

Key Points

• Madhubani Painting :
  • Madhubani painting, also referred to as Mithila Art (as it flourishes in the Mithila region of Bihar), is characterized by line drawings filled in by bright colours and contrasts or patterns. Hence pair 1 is correctly matched.
