ML Aggarwal Class 10 ICSE Maths Solutions

** ****Question 1. **Draw a histogram for the following frequency distribution and find the mode from the graph **:**

**Answer :**

Mode = 14

**Question 2. **A Mathematics aptitude test of 50 students was recorded as follows :

Draw a histogram for the above data using a graph paper and locate the mode. (2011)

**Answer :**

Hence, the required mode is 82.5.

**Question 3. **Draw a histogram and estimate the mode for the following frequency distribution :

**Answer :**

Representing classes on x-axis and frequency on the y-axis,

we draw a histogram as shown.

In the histogram, join AB and CD intersecting at M.

From M, draw ML perpendicular to the x-axis. L shows the mode

Hence Mode = 23

**Question 4. **Using a graph paper draw a histogram for the given distribution showing the number of runs scored by 50 batsmen. Estimate the mode of the data

**Answer :**

**Question 5. **Use a graph paper for this question. The daily pocket expenses of 200 students in a school are given below:

Draw a histogram representing the above distribution and estimate the mode from the graph.

**Answer :**

Mark the upper comers of the highest rectangle

and the corners of the adjacent rectangles as A, B, C, D as shown.

Join AC and BD to intersect at P. Draw PM ⊥ x-axis.

Then the abscissa of M is 21, which is the required mode.

Hence, mode = 21

**Question 6. **Draw a histogram for the following distribution** :**

Hence estimate the modal weight.

**Answer :**

We write the given distribution in the continuous form :

Representing the weight (in kg) on x-axis

and No. of students on y-axis. We draw a histogram as shown.

Now join AB and CD intersecting each other at M.

From M, draw ML perpendicular to x-axis.

L is the mode which is 51.5 kg

**Question 7. **Find the mode of the following distribution by drawing a histogram

Also state the modal class.

**Answer :**

Representing class on x-axis and frequency on the y-axis,

we draw a histogram as shown.

Join AB and CD intersecting each other at M.

From M, draw ML perpendicular to the x-axis.

L shows the mode which is 30.5 and class is 27-33.
