  RD Sharma Solutions For Class 7 Chapter 24 – Data Handling – III (Constructions of Bar graphs) 1. Two hundred students of class VI and VII were asked to name their favorite colours so as to decide upon what should be the colour of their school house. The results are shown in the following table. Colour: Red Green Blue Yellow Orange Number of Students 43 19 55 49 34 Represent the given data on a bar graph. (i) Which is the most preferred colour and which is the least? (ii) How many colours are there in all? Solution: Steps of constructing bar graph: 1. Mark the horizontal axis OX as Name of the Colour and the vertical axis OY as Number of Students. 2. Along the horizontal axis OX, choose bars of uniform (equal) width, with a uniform gap between them. 3. Choose a suitable scale to determine the heights of the bars, according to the space available for the graph. Here, we choose 1 small division to represent 10 students. (i) The most preferred colour is blue and the least preferred ...

NCERT Solutions for Class 6 Chapter 14: Practical Geometry

  NCERT Solutions for Class 6 Chapter 14: Practical Geometry Exercise 14.1 page no: 276 1. Draw a circle of radius 3.2 cm. Solutions: The required circle may be drawn as follows: Step 1: For the required radius 3.2 cm, first open the compasses. Step 2: For the centre of a circle, mark a point ‘O’. Step 3: Place a pointer of compasses on ‘O’. Step 4: Now, turn the compasses slowly to draw the required circle. 2. With the same centre O, draw two circles of radii 4 cm and 2.5 cm. Solutions: The required circle may be drawn as follows: Step 1: For the required radius 4 cm, first open the compasses Step 2: For the centre of a circle, mark a point ‘O’ Step 3: Place a pointer of compasses on ‘O’. Step 4: Turn the compasses slowly to draw the circle. Step 5: Next, open the compasses for 2.5 cm. Step 6: Again place a pointer of compasses on ‘O’ and turn the compasses slowly to draw the circle. 3. Draw a circle and any two of its diameters. If you join the ends of these diameters, what is th...
