Among the following, the correct picture representation of the number of school teachers in Delhi is:
Show Hint
When solving pictograph problems, calculate the value represented by each symbol and then determine the number of symbols required for the given number of items.
In the given pictograph, the number of school teachers is represented by each symbol.
The number of teachers in Hyderabad is 4200, represented by 7 symbols.
The number of teachers in Chennai is 3000, represented by 5 symbols.
To find the correct number of symbols for Delhi, we need to determine the ratio between the symbols and the actual number of teachers.
Each symbol represents:
\[
\text{Value of each symbol} = \frac{4200}{7} = 600
\]
Now, for Delhi, the total number of teachers is 2400. The number of symbols required is:
\[
\text{Number of symbols for Delhi} = \frac{2400}{600} = 4
\]
Therefore, the correct representation of the number of teachers in Delhi is 4 symbols, which corresponds to option (1).
