Answer Posted / akbar
here we have 5 part shave lotion(S) and 3 part water(W) so
mixture will be 5 + 3 = 8 part. we are removing some part
say X from mixture (ie 8 part) and again adding X part
water in it. so final mixture remains same 8 part. now we
will be having equal part of S and W which is nothing but 4
part S and 4 Part W. so X must be 3 = 1S + 2W
5 + 3 = 8;
8 - 3(ie 1S + 2W) = 5;
5 + 3W = 8(4S + 4W);
