1.) Number of Total People = 1387

In Figure 1, Red boxes represent "Teens" which is 10 in number whereas Blue boxes represent "Adults".

1 box contains = 1387/19 = 73

Number of Teens = 73 * 10 = 730 

In short, Your Final Answer would be: 730 

2.) Number of Total Chocolates = 1440 

In Figure 2, Red boxes represent "Chocolate flavor ice-cream" which is 6 in number whereas Blue boxes represent "Vanila".

1 box contains = 1440/15 = 96

Number of Chocolate Ice-creams = 96 * 6 = 576

In short, Your Final Answer would be: 576

3.) Number of Total Sodas = 576

In Figure 3, Red boxes represent "diet sodas" which is 5 in number whereas Blue boxes represent "Regular sodas".

1 box contains = 576/12 = 48 sodas

Number of diet cokes = 48 * 5 = 240 

In short, Your Final Answer would be: 240 

Hope this helps!
