  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 11: Algebra

  NCERT Solutions for Class 6 Chapter 11: Algebra Exercise 11.1 Page no: 226 1. Find the rule which gives the number of matchsticks required to make the following matchsticks patterns. Use a variable to write the rule. (a) A pattern of letter T as (b) A pattern of letter Z as (c) A pattern of letter U as (d) A pattern of letter Vas (e) A pattern of letter E as (f) A pattern of letter S as (g) A pattern of letter A as Solutions: (a) From the figure we observe that two matchsticks are required to make a letter T. Hence, the pattern is 2n (b) From the figure we observe that three matchsticks are required to make a letter Z. Hence, the pattern is 3n (c) From the figure we observe that three matchsticks are required to make a letter U. Hence, the pattern is 3n (d) From the figure we observe that two matchsticks are required to make a letter V. Hence, the pattern is 2n (e) From the figure we observe that 5 matchsticks are required to make a letter E. Hence, the pattern is 5n (f) From the...
