Answer:

14) B. 12

15) A. 19

Step-by-step explanation:

There's an error in the 14th Question, let's tackle them by calculations appropriately:

Given:

  1. Rectangle (2D)
  2. Circle (2D)

We all know that half of one part either represented as a fraction or integer is equal to the other half

Rectangle

5 + 7 + 7 + x = 2 + 3 + 15 + 11

Note: we are representing the unknown as "x"

19 + x = 31

x = 31 - 19

x = 12

Therefore, the value of the unknown part is 12

Circle

x + 36 + 25 + 27 = 33 + 21 + 30 + 23

x + 88 = 107

x = 107 - 88

x = 19

Therefore, the value of the unknown part in Question 15 is 19

Answer: (A) 19

Step-by-step explanation:

    We will find the value of the question mark in Question 15. We are given a circle that is split into several sections. I will assume that these lines represent the diameter and all bisect each other in the center.

    With this information in mind, we can create an equation to solve. Let the question mark be equal to x. We will take four of the sections and set them equal to the other four, cutting this figure in half.

         x + 36 + 25 + 27 = 33 + 21 + 30 + 23

         x + 88 = 107

         x + 88 - 88 = 107 - 88

         x = 19

    The value of the question mark (?) is equal to (A) 19.
