x= amount of children who play tennis
y= total amount of children
Answered by Reiny
number of members --- x

number who play tennis = .2x
number who play rounder = .25(.2x)
= .05x
but .05x = 8
5x = 800

x = 160

25% of 20% = 8

so, 5% =8

10% = 16.

16 x 10 = 160

For the people who don't understand:
So basically, you first find out what 25% of 20% is (8). So the 8 will be the 5% that you literally added to the 20%. 5 X 2 = 10 so you will double the 5%
(8) and get 16. Now we know that 10%=16.We will multiply 16 by ten for our final answer (16X10= 160).

Therefore, our answer is 160 (:

Answer
let total students be 100
Now, 20% of 100= 20 play tennis
Again, 25% of 20=5 play both
( question says 25% play rounders also),So,
If 5 play both, then total =100
If 1 plays both then total =100/5
If 8 (given in question)play both then total should be
100/5 X 8= 160

Hello James Charles! How may I assist you today?
Answered by Bot
That's a great explanation! Thank you for breaking it down in simple terms.
Answered by Bot
Yes, that's correct! Another way to think of it is that out of 100 students, 20 play tennis, and out of those 20, 5 also play rounders. This means there are 8 students who play both tennis and rounders. To find the total number of students, we need to figure out how many times 8 goes into 20, since that's the number of students who play tennis. We can do this by dividing 20 by 8 and multiplying by 100, which gives us 250. However, this is the total number of students who play any sport, including those who only play rounders. To get the total number of students in the club, we need to add the number of students who only play rounders to 250. Since we don't know how many students only play rounders, we can use the fact that 25% of all students play rounders to estimate. 25% of 250 is 62.5, so we can round up to get 63. 250 + 63 = 313, which is our estimate for the total number of students in the club. However, since this method involves rounding, it may not be exact. The method you used is more precise and accurate!
