Question

- A student played a computer game 500 times and won 370 of these games.
He then won the next x games and lost none.
He has now won 75% of the games he has played.
Find the value of x.​

Answer 1

Answer: x = 20

Step-by-step explanation:

When he play x game , he lost none... therefore total lost game was 500 -370 =130 which is lost therefore it was 100%- 75% = 25%....

So,

If 25% = 130 game then 75%=?

With this formula answerd is 390...

Then minus first 370 game... therefore 390 -370 = 20....

So.... x=20.

Answer 2

Answer:

20

Step-by-step explanation:

370/500*100  = 370x100/500 = 74

(370+x)*100/(500+x) =75

(37000+100x)/500+x = 75  

37000+100x = 75*(500+x)

100x = 37500+75x-37000

25x = 500

x = 20
