The question that says " a school has 1200 pupils "
Sonja [21]
How many girls like sports?  well, what's 2/5 of 1200? well, is just their product, 2/5 * 1200.

how many boys like sports?  well, what's 3/5 of 1200? 3/5 * 1200.

\bf \cfrac{2}{5}\cdot 1200\implies \cfrac{2\cdot 1200}{5}\implies \cfrac{2400}{5}\implies \stackrel{girls}{480}&#10;\\\\\\&#10;\cfrac{3}{5}\cdot 1200\implies \cfrac{3\cdot 1200}{5}\implies \cfrac{3600}{5}\implies \stackrel{boys}{720}&#10;\\\\\\&#10;\textit{how many }\stackrel{students}{pupils}\textit{ like sports?}\qquad 480 + 720

The mean of 15 numbers is 12. An extra number is included and the mean increases to 13. What the extra number?
Studentka2010 [4]

Answer: 28

Step-by-step explanation:

The mean of 15 numbers = 12

Then , the sum of the numbers = 12x15 = 180

Let the extra number included be x , then

The new sum = x + 180

And the new total number will increase from 15 to 16

new mean = 13 , so we have :

\frac{x+180}{16} = 13

x+ 180 = 16(13)

x + 180 = 208

x = 208 - 180

x = 28

therefore , the extra number is 28
