Each of three friends, A, B and C, has a certain number of marbles with him, such that the number of marbles with B is 12% more than that with C and 12% less than that with A and C together. If the number of marbles with B is less than 500, then find the total number of marbles with all the three friends.

a)658

b)940

c)846

d)Cannot be determined

My approach :

number of marbles with

C = 100x 

B = 112x

A= y

B is 12% less than A+C, so 

112x = 0.88( y + 100x) 

100x. 24 = 88y 

300x = 11y      --------------1

Also given , B is less than 500

112x less than 500

x less than 4.46

x = { 1,2,3,4  }

but from equation 1, x has to be of form 11k

so it's a contradiction. where did i go wrong ?
