A pictograph is a graph that shows numerical information by using picture symbols or icons to represent data sets. The advantage of using a pictograph is that it is easy to read and understan.

The pie chart shows that 30 % of the people like mango.
If a total of 30 people were surveyed, the number of people who like mango is given by
$30\%\text{of}30=\frac{30}{100}\times 30=9.$
Thus, 9 people chose mango as their favourite fruit.

On observing the graph, we see that 35% of 200 people prefer to watch TV.

$35\%\text{of}200=\frac{35}{100}\times 200=35\times 2=70$
$\therefore$ 70 people regard watching TV as their favourite leisure time activity.

Given:
1 pizza picture = 100 pizzas
$\therefore$ $\frac{1}{2}$ pizza picture = 50 pizzas
Number of pizzas sold by Super Pizza
$=100+100+100+100=400$
Number of pizzas sold by Choice Pizza
$=100+100+100+50=350$
$\therefore$ Number of more pizzas sold by Super Pizza than Choice Pizza
$=350-400=50$

By observing the pictograph, we see that Pizza Village has the least number of pictures of pizzas beside it.

$\therefore$ Pizza Village sold the least number of pizzas.

Total amount spent = ₹ 7,20,000

Amount spent on basketball
$=35\%\text{of}₹7,20,000$
$=\frac{35}{100}\times ₹7,20,000=₹2,52,000$

$\therefore$ The amount spent on basketball is ₹2,52,000.

On observing the above graph, 20% of the people prefer listening to music during their leisure time.

On observing the graph, we see that the smallest sector of the graph (5%) represents "Fitness exercise". Therefore, the least preferred activity of people is "Fitness exercise".

On observing the graph, we see that 10% of people prefer to play games.

Total amount spent = ₹ 3,60,000

Amount spent on Hockey
$=30\%\text{of}₹3,60,000$
$=\frac{30}{100}\times ₹3,60,000=₹1,08,000$

$\therefore$ The amount spent on Hockey is ₹ 1,08,000.
