## AP Board Class 7th Maths Chapter 7 Data Handling Ex 3 Textbooks Solutions with Answer PDF Download

Find below the list of all AP Board Class 7th Maths Chapter 7 Data Handling Ex 3 Textbook Solutions for PDF’s for you to download and prepare for the upcoming exams:Question 1.

Say true or false and why?

(i) The difference between the largest and smallest observations in a data set is called the

mean.

(ii) In a bar graph, the bar which has greater length indicates mode.

(iii) Value of every observation in the data set is taken into account when median is calculated.

(iv) The median of a set of numbers is always one of the numbers

Solution:

i) False

ii) True

iii) False.

We take only the mid value when the observations are arranged either in ascending / descending order.

iv) False

It may or may not be in the data set.

Question 2.

The monthly income (in rupees) of 7 households in a village are 1200, 1500, 1400, 1000, 1000, 1600, 10000. (i) Find the median income of the house holds. (ii) If one more household with monthly income of 1500 is added, what will the median income be?

Solution:

Given that

The household incomes in Rs. are 1200, 1500. 1400, 1000, 1000, 1600, 10,000

Arranging these observations in ascending order 1000, 1000, 1200, 1400, 1500, 1600, 10,000

Medían is the mid value = Rs. 1400

If one more household with income Rs. 1500 ¡s added them the data becomes

1000, 1000, 1200. 1400, 1500, 1500, 1600, 10,000

Now the median = average of 1400 and 1500

= 1400+15002=29002 = Rs.1450

Question 3.

Observations of a data are 16, 72,0, 55, 65, 55, 10, and 41. Chaitanya calculated the mode and median without taking the zero into consideration. Did Chaitanya do the right thing?

Solution:

Mode is correct but median is wrong.

Question 4.

How many distinct sets of three positive integers have a mean of 6, a median of 7, and no mode?

Solution:

It is not possible

Question 5.

Four integers arc added to a group of integers 3,4,5,5 and 8 and the mean, median, and mode of the data increases by 1 each. What is the greatest integer in the new group of integers?

Solution:

Given set of integers = 3, 4, 5, 5 and 8

The mean of the given data = Sum of the integers Number of integers =3+4+5+5+85=255 = 5

The median of the given data 3. 4. 5, 5. 8 (already in ascending order) = 5 (the mid

Mode of the given data 3. 4. 5. 58 iS 5.

After adding 4 integers the mean, mode and median increased by 1

New

Mean = 5 + 1 = 6

Median = 5 + 1 = 6

Mode = 5 + 1 = 6

Now sum of the (5 + 4 = 9) numbers = Number of integers × average

Sum = 9 × 6 = 54

But sum of the given set of 5 numbers = 25

∴ Sum of the newly added 4 numbers = 54 – 25 = 29

Mode = 6 means 6 should appear for 3 times.

But sum of four numbers = 29

29 = 6 + 6 + 6 + fourth number

29 = 18 + fourth number

∴ fourth number = 29 – 18 = 11
