Shapes - Free MCQ Practice Test with solutions, Class 3 Mathematics

Figure A is a square divided in 4 parts. Figure B is a circle divided in 2 parts. Figure C is a pentagon divided in 3 parts. Figure b is a hexagon divided in 6 parts. Hence, Figures A. B and D have even number of parts, but Figure C has odd number of parts and hence C is different from the rest.

The point is moving clockwise at a distance equal to half the length of side from the point in the previous term.

Within each term each letter skips 2 alphabets to reach next; the next term starts with the letter following the last alphabet in the term before.

The 1st term has 1 dot inside the rectangle. The 2nd term has 2 (1 + 1) dots inside the rectangle. The 3rd term has 3(2 + 1) dots inside the rectangle. The 4th term has 4(3 + 1) dots inside the rectangle. The 5th term has 5(4 + 1) dots inside the rectangle.

The difference between two terms is 2 in decrease order.
32 - 2 = 30
30 - 2 = 28
28 - 2 = 26
26 - 2 = 24

To determine the rule of the pattern, let's examine the differences between consecutive terms:
Given sequence: 2, 5, 11, 23, 47
(2 x 2) + 1 = 5
(5 x 2) + 1 = 11
(11 x 2) + 1 = 23
(23 x 2) + 1 = 47
Each term is obtained by multiplying the previous term by 2 and adding 1.
The correct answer is: a) Multiply the number by 2 and add 1

The rule of the pattern is to add 4
34 + 4 = 38
38 + 4 = 42
42 + 4 = 46
46 + 4 = 50
50 + 4 = 54

The first term has 1 square. The 2nd term has 3 (1 + 2) squares. The 3rd term has 5 (3 + 2) squares. The 4th term has 7 (5 + 2) squares. The 5th term will have 9 (7 + 2) squares.

The list of the number will be 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64........
Let's Check the statements:
A: 24 is the 2nd number → The 2nd number is 16, not 24 (False)
B: 29 is in the list → The numbers go 28, 32… 29 is not in the list (False)
C: 60 is the 13th number → Count: 12(1), 16(2), … 60(13) (True)
D: 35 is not in the list → Numbers jump by 4: 32, 36… 35 is not in the list (True)

Correct Option: D
