plz anybody hel with this question​

Answer 1

Answer:

The percentage of students got prizes $=12\frac{8}{9}$%

Step-by-step explanation:

40% of 36,000 candidates were girls

Number of girl candidates $=\frac{40}{100} . 36000$ $=14,400$

∴ Number of boy candidates $=36,000 - 14,400$ $=21,600$

Number of boy's got prizes $=\frac{15}{100} . 21600$ $=3,240$

Number of girl's got prizes $=\frac{10}{100} . 14,400$ $=1,440$

Total Number of students got prizes $= 3,240 + 1,440$ $= 4,640$

∴ The percentage of students got prizes $=\frac{4,640}{36,000} . 100$% $=\frac{116}{9}$% $=12\frac{8}{9}$%
