Question

According to the information provided in the table, a gaming company concludes that if they can double the number of 19- to 22-year old playing sports game, and increase the number of sports gamers in the 9- to 13-year old age group, they will have equal total numbers of players for each game type if they double the number of players of adventure games in which age group?

Age Group	First Person Shooters	Sports Games	Adventure Games	Total
9-to 13-year olds	16000000	9000000	25000000	50000000
14- to 18-year olds	48000000	13000000	31000000	82000000
19-to 22-year olds	38000000	27000000	19000000	84000000
23- to 60-year olds	8000000	3000000	10000000	21000000

• A. 23- to 60-year olds
• B. 19- to 22-year olds
• C. 14- to 18-year olds
• D. 9- to 13-year olds

Answer 1

The correct option is D 9- to 13-year olds

$\Rightarrow$ Total number of first person shooters $=16,000,000+48,000,000+38,000,000+8,000,000$

$=110,000,000$

$\Rightarrow$ Total number of people playing sports game $=9,000,000+13,000,000+27,000,000+3,000,000$

$=52,000,000$

$\Rightarrow$ Total number of people playing adventure game $=25,000,000+31,000,000+19,000,000+10,000,000$

$=85,000,000$

$\Rightarrow$ We don't know by how much the $9-to13-year$ old group will increase in sport game preference, but presumably the increase will be made to match the currently largest group, first person shooters.

$\therefore$ In order to raise adventure games to the level of first person shooters, we need to add $110,000,000-85,000,000=25,000,000$ gamers to the adventure games group.

$\Rightarrow$ If we are going to do so by doubling one of the age groups, then $25,000,000$ is equal to the size of the current group. $9-to13-year$ olds currently have $25,000,000$ preferring adventure games.

$\therefore$ Correct answer is option $D$.
