## Sandeep Garg Solutions Class 11 – Chapter 1

Question 1

Mentioned below are the marks acquired by 40 employees during their assessment. Arrange the marks in ascending and descending orders.

 10 15 18 15 9 6 5 3 9 6 22 15 12 20 1 5 6 4 10 3 21 12 11 19 3 10 10 26 19 10 10 17 28 22 5 21 17 8 9 11

Marks in ascending Order:

1,3,3,3,4,5,5,5,6,6,6,8,8,9,9,10,10,10,10,10,10,11,11,12,12,15,15,15,17,17,18,19,19,20,21,21,22,22,26,28

Marks in descending Order:

28,26,22,22,21,21,20,19,19,18,17,17,15,15,15,12,12,11,11,10,10,10,10,10,10,9,9,8,8,6,6,6,5,5,5,4,3,3,3,1

Question 2

The heights of 36 students (in inches) are given below. Arrange the following data in an individual frequency sequence.

 60 72 68 68 58 55 50 72 55 50 66 66 62 55 66 66 58 72 72 60 55 60 55 58 60 66 72 72 60 68 55 58 65 60 68 55

In the form of frequency distribution, the given data can be arranged as follows.

 Heights (in inches) Marks Frequency 50 $\large&space;II$ 2 55 $\large&space;\bcancel{IIII}&space;II$ 7 58 $\large&space;IIII$ 4 60 $\large&space;\bcancel{IIII}&space;I$ 6 62 $\large&space;I$ 1 65 $\large&space;I$ 1 66 $\large&space;\bcancel{IIII}$ 5 68 $\large&space;IIII$ 4 72 $\large&space;\bcancel{IIII}&space;I$ 6 $$\begin{array}{l}\sum f\end{array}$$ = 36

Question 3

Find the missing class interval.

 Class-Interval Below 20 20âˆ’50 50âˆ’90 90âˆ’140 More than 140 Frequency 8 11 15 3 5

In the above-mentioned question, the class interval has a different width. Therefore, the missing class interval cannot be established.

Question 4

Transfer the given cumulative frequency series to simple frequency series.

 Marks Number of Students Less than 10 12 Less than 30 19 Less than 50 26 Less than 70 48 Less than 90 57

The cumulative frequency of ‘less than’ is displayed in ‘simple frequency distribution’ form.

 Class-Interval Frequency 0 – 10 10 – 30 30 – 50 50 – 70 70 – 90 12 19 âˆ’ 12 = 7 26 âˆ’ 19 = 7 48 âˆ’ 26 = 22 57 âˆ’ 48 = 9

Question 5

From the following data, arrange a frequency distribution table with classes 10-20, 20-30, etc.

 25 10 12 26 10 32 36 31 41 55 22 31 36 38 25 11 12 25 42 48 47 37 45 54 42 35 37 32 65 75

 Class interval Tally marks Frequency 10-20 $\large&space;\bcancel{IIII}$ 5 20-30 $\large&space;\bcancel{IIII}$ 5 30-40 $\large&space;\bcancel{IIII}$ $\large&space;\bcancel{IIII}$ 10 40-50 $\large&space;\bcancel{IIII}&space;I$ 6 50-60 $\large&space;II$ 2 60-70 $\large&space;I$ 1 70-80 $\large&space;I$ 1 $$\begin{array}{l}\sum f\end{array}$$ = 30
