Question Discussion & Solution

Given equation: 49 A 7 B 5 C 6 = ?

After interchanging alphabets: 49 ÷ 7 + 5 × 6 = ?

7 + 30

37

Hence, ‘37’ is the answer.

The Correct answer is Uniform motion.

Key Points

• Motion​:
  • It is a phenomenon in which an object changes its position with respect to time.
  • All motions are relative to some frame of reference. 
  • There are two types of motion:
    • Uniform Motion
    • Non-uniform Motion
• Uniform motion:
  • If an object is traveling with uniform motion, it is moving in a straight line at a constant speed.
  • For example, An object falling at terminal velocity experiences the same air resistance as its weight.
  • Newton's first law can be used to explain the movement of objects traveling with uniform motion.
  • Newton's first law is a body that is at rest or moving at a uniform rate in a straight line will remain in that state until some force is applied to it.

​Additional Information

• Retarding motion: The Motion in which the speed of the body gradually decreases.
• Non-uniform motion: If a body covers unequal distances in equal intervals of time
• Non-linear Motion: Nonlinear motion is motion along a curved path; It is the combination of two components of motion' horizontal motion (without acceleration) vertical motion (under the acceleration of gravity).

Refrigerator, furniture and television are needed in one house but these are not the necessary things. Without these three a house can be built but without the walls a house cannot be built.

The pattern followed here is:

Hence, ‘DW’ complete the series.

Let Rahul’s age be x.

Let Rita’s age be y.

Let Ekta’s age be z.

⇒ x = y + 3

⇒ y = 4z – 3

⇒ x = 4z – 3 + 3

⇒ x = 4z

⇒ x/z = 4

⇒ x ∶ z = 4 ∶ 1
