Hey Sukundhitara,

I don't know where you got that question, but that can't possibly be the whole thing, unless it's a terrible question. When posting here on the forums, please don't simplify or paraphrase, but post the question in its entirety. To answer this one, we need to know if the order of the beads matters, and also if Sunita needs to use all 8 beads, or if she can make the necklace with only some of the beads.

However, if that is the whole question, I deeply recommend you don't do any more questions from whatever source that comes from.
