Quantitative Reasoning Examples and Solutions For Pry 3, 4 & 5

Quantitative Reasoning measures a person’s ability to use mathematical or analytical skills to solve problems. Here, I will solve some examples of quantitative reasoning for primary 3, 4, and 5 pupils.

Example 1

Quantitative reasoning

Solution

One good thing about quantitative reasoning is that it helps you think deeply to generate the right answer.

The technique used in the above example follows this pattern;

(2*3) – 5 = 1

(16*3) – 5 = 43

(27*3) – 5 = 76

(40*3) – 5 = 115

Use this format to solve the remaining question

(10*3) – 5 = 25

(15*3) – 5 = 40

(33*3) – 5 = 94

(54*3) – 5 = 157

Example 2

Quantitative reasoning

Solution

The format to solve this particular question is discussed below;

139 * 3 = 417

258 * 2 = 516

To solve the first question,

113 * 5 = 565

Therefore, 6 will be in the box

Example 3

Quantitative reasoning

Solution

(9*4) divided by square root of 9 = 36/3 = 12

(36*5) / square root of 36 = 180/6 = 30

(64*2)/ square root of 64 = 128/8 = 16

Example 4

Quantitative reasoning

Solution

The numbers in COLUMN must be the same in the ROW

For ROW 1, the numbers are 1, 2, 3, 0, 1

For COLUMN 1, the numbers are 1, 2, G, 0, T

The G is 3

The T is 1

So, use the same method for the rest.

Example 5

quantitative reasoning question

Solution

For the first sample question, take the 2 and 2 in the square boxes to be 22 and multiply the 3 and 6 in the triangle boxes. then subtract i.e. 22-(6*3) = 4 in the circular box

2nd sample: 18-(2*5) = 8

sample 3: 22-(7*3) = 1

Use this approach to solve questions 6-10 of the diagram

Example 6

quetion on quantitative reasoning for primary

Solution

From the samples given, adding the first two columns together will give the third column.

1st example, 4118 + 5420 = 9538

2nd example, 1257 + 3482 = 4739

Also, subtracting the first column from the second column will give you the fourth column.

sample 1, 5420 – 4118 = 1302

sample 2, 3482 – 1257 = 2225

Use this same method to solve questions 1-5 of the diagram

Example 7

quantitative reasoning

Solution

If you look at the first example, add the left-hand side together (7+5+4+3 = 19) and the right-hand side (9+12+15+21 =57). So if you multiply the sum of the left-hand side, which is 19 x 3, you will get the sum of the right-hand side, which is 57

The same for the second example, the left-hand side is 12+5+13+8 = 38, and the right-hand side is 24+36+15+39 = 114. if you multiply the 38 x 3 = 114

In summary, if you add the numbers on the left-hand side and multiply by 3, you will get the sum of the numbers on the right-hand side.

Example 8

Example 9

quantitative reasoning

Solution

(34/2) + 6 = 23

(49/2) + 6 = 30 1/2

(62/2) + 6 = 37

(76/2) + 6 = 44

The above format should be used to solve the problem.
Example 10
quantitative reasoning primary
Solution

For the first sample, the format is

(2+2+1+3)*3=24

(0+4+3+6)*3 =39

(4+1+2+4)*3=33

You add all the numbers at the edge of the diagram and multiply by 3

For the second sample,

2*8=12+4=16

5*9=17+28=45

7*7=25+24=49

Example 11

quantitative reasoning more

From the example, 25/5 = 5, 20-10 = 10

Then add the two answers 5+10 = 15, which is the number in the middle

For the second one, 39/13 = 3, 46-18 = 28, so 28+3 = 31

For the third one, 44/2 = 23, 11-6 = 5, so 23+5 = 28

Example 12

quantitative reasoning question

For sample 1, (2^2 + 5^2) -(3^2 + 2^2) = 16

(4 +25) – (9+4) = 16

29-13 = 16

For sample 2, (3^2 + 1^2) – (1^2 + 2^2) = 5

(9 + 1) – (1 + 4) = 5

10 – 5 = 5

For sample 3, (5^2 + 5^2) – (4^2 + 2^2) = 30

(25 + 25) – (16 + 4) = 30

50 – 20 = 30

So, you can use the above approach to solve the remaining questions.
