250/11 = 22 soaps + 8 unused scraps
from 22 soaps u get 22 scraps
so now u have 30 scraps which means 2 soaps more and then 8 scraps left unused and 2 scraps u get from 2 soaps

=> 24 soaps and 10 scraps at the end

is it possible? think again and chek' the question. 1/3 of person ahead of her and 2/3 behind her when added gives the total of participants which includes persons ahead of her and persons behind her along with her!!!!!!
