Lela and pepe are playing a video game. the ratio of lela’s game score to pepe's score is 2 : 5. then lela completes a quest and scores 12 bonus points. the new ratio becomes 7 : 10. what is lela’s score originally?

       Lela's original score was 16.

Step-by-step explanation:

Alright lets get started.

Suppose Lela score was L.

Suppose Pepe score was  P.

The ratio of Lela’s game score to Pepe's score is

So the equation will be

Cross multiplying

.................equation 1

Then Lela completes a quest and scores 12 bonus points. The new ratio becomes

Cross multiplying

Plugging value of P from equation 1

Hence the score of Leela originally was 16.                Answer

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
