If you have scored 5 to 8 marks, then you are doing well, keep it up. If you have scored less than 5 marks then you need to work a little harder on this subject. But don&#39;t worry, we are here to help you master the subject.

Let&#39;s check the answers and solutions and try to find out what went wrong. 
 

<h2>Answers and Solutions</h2>

Q:1 The correct answer is Option 2 i.e. 66.

The total score of 15 innings = 70 × 15 = 1050

The total score of 16 innings = 1050 + 6 = 1056

∴ Average score of 16 innings = 1056/16 = 66

 

Q:2 The correct answer is option 2 i.e. 38.5 kg.

Average weight = The sum of total weight/number of people

The sum of the weight of students of class VI = (58 × 39) = 2262 kg

The sum of the weight of students of class VII = 52 × 36.5 = 1898 kg

The sum of the weight of students of class VIII = (50 × 40) = 2000 kg

The sum of the weight of total students of all the class = (2262 + 1898 + 2000) = 6160 kg

The total number of students = (58 + 52 + 50) = 160 [given]

The average weight of 160 students = 6160/160 = 38.5 kg

 

Q:3 The correct answer is option 3 i.e. 40 kg.

Given, Total students = 20

1 student of 30 kg is replaced and the average increased by 0.50 kg.

New student&#39;s weight = Weight of replaced student + (average increase × Total number of students)

Hence, Weight of new student = 30 + (0.50 × 20) = 30 + 10 = 40 kg

 

Q:4 The correct answer is option 1 i.e. 19.75

Average = Sum of total numbers/total numbers

The sum of the first 15 numbers = 15 × 18.5 = 277.5

The sum of the next 15 numbers = 15 × 21 = 315

The sum of total 30 numbers = 277.5 + 315 = 592.5

The average of 30 numbers = 592.5/30 = 19.75

 

Q:5 The correct answer is option 4 i.e. 29000

Total expenditure on workers = 5 × 20,000

⇒ 1,00,000

Total expenditure on clerks = 3 × 30,000

⇒ 90,000

Total expenditure on managers = 2 × 50,000

⇒ 1,00,000

Total expenditure = 1,00,000 + 1,00,000 + 90,000

⇒ 2,90,000

Average = 2,90,000/(5 + 3 + 2)

⇒ 29000

 

Q:6 The correct answer is Option 1 i.e. 44.6 kg

The average weight of 22 girls is 46 kg,

Sum of weight of 22 girls = 46 × 22 = 1012 kg

The average weight of 28 girls is 54 kg

Sum of weight of 28 girls = 54 × 28 = 1512 kg

The average weight of the other 20 girls is 30 kg

Sum of weight of 20 girls = 30 × 20 = 600 kg

Sum of weight of all girls = 1012 + 1512 + 600 = 3124 kg

Total number of girls = 22 + 28 + 20 = 70

Average weight of all the girls = 3124/70 = 44.6 kg 

 

Q:7 The correct option is option 2 i.e. 30 Kg

Total weight of 23 students = 23(37) = 851 Kg

After, Manish replaced Ravi the total weight becomes 845 Kg

There is a reduction of 6 Kg,

Thus, Manish&#39;s weight is;

⇒ 36 - 6 = 30 Kg

 

Q:8 The correct answer is option 3 i.e. 20 years.

Average = Sum of total age/number of boys

The average age of 30 boys = 17.5 years = 210 months

The age of the boy who leaves = 17.5 years = 210 months

If one boy replaces with the new one average becomes

⇒ 17.5 years + 1 month = 211 months

Let the age of the new boy = x years

A/Q,

30 × 210 - 210 + x = 211 × 30

⇒ 6300 - 210 + x = 6330

⇒ x = 240 months = 20 years

The age of new boy = 20 years

 

Q:9 The correct answer is Option 4 i.e. 7.

Let there be &#39;n&#39; friends in the group

The sum of all observations = Average × Number of observations

⇒ 476 = 68 × n

⇒ n = 476/68 = 7

 

Q:10 The correct answer is Option 1 i.e. 36.

Let the average temperature for the first week and the following weeks be x1, x2, x3, and x4. Therefore, we get

<table border="1" cellpadding="1" cellspacing="1">
	<tbody>
		<tr>
			<td>(x1 + x2 + x3)/3 = 35</td>
			<td>(x2 + x3 + x4)/3 = 39</td>
		</tr>
		<tr>
			<td>x1 + x2 + x3 = 35 × 3</td>
			<td>x2 + x3 + x4 = 39 × 3</td>
		</tr>
		<tr>
			<td>x1 + x2 + x3 = 105</td>
			<td>x2 + x3 + x4 = 117</td>
		</tr>
	</tbody>
</table>

Now, from this, we can get:

⇒ (x2 + x3 + x4 ) - ( x1 + x2 + x3 ) = 117 - 105

⇒ x4 - x1 = 12

⇒ x1 : x4 = 9 : 13 (Given)

Therefore,

⇒ 13x - 9x = 12 

⇒ x = 12/4 

⇒ x = 3

x1 = 9 × 3 = 27 and x4 = 13 × 3 = 39

And we get:

⇒ x2 + x3 = 105 - 27

⇒ x2 + x3  = 78

Final answer = (x1 + x2 + x3 + x4)/4 = (27 + 78 + 39)/4 = 144/4 = 36
