Narcisse and aristide have numbers of arcade tokens in the ratio 7 : 3, respectively. narcisse gives aristide some of his tokens, and the new ratio is 6 : 5. what is the least number of tokens that narcisse could have given to aristide? a. 9b. 17c. 21d. 27e. 53

Narcisse could have given 17

Step-by-step explanation:

Given that Narcisse and Aristide have numbers of arcade tokens in the ratio 7 : 3

Let Narcisse have 7x and Aristide 3x respectively

If d tokens are given from Narcisse to Aristide, new belongings

7x-d, 3x+d

Ratio is 6:5

i.e. So x should be a multiple of 11

least number of x =11

Verify:

Narcisse and Aristide have intially 77 and 33.

Narcisse gave 17 to Aristide

New are 60 and 50 making ratio 6:5

So answer is 17

answer is b

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
