Rachel has 60 scones. She sells them to Robbie , Cameron , Lou’s , Tom and Charlie in that order. Each customer buys more scones than the last and the increase is the same number in each case . Robbie and Cameron’s combined total number of scones is three sevenths of the total of Louis , Tom and Charlie . How many scones does each boy buy ?

Respuesta :

suppose robbie buys x scones then according to the question.....cameron will have x+y
..lou's will have (x+y)+y=x+2y ...
Tom=x+3y....
Charlie=x+4y.....
now as we know that the combines scones of robbie and Cameron is 3/7 times of total of louis.....
x+(x+y)=3/7 (x+3y+x+2y+x+4y)....solve this ...and this will be your 1st equation...and second equation will be x+x+2y+x+3y+x+4y=60.......And solve both equation simultaneously and then you will have the answers of x and y the put the values of x and y in each of the equation that i have written above for each person
