In most cases the Court does not need to see bank statements when you go bankrupt. As you mention the need for them to have 3 months, I think this is probably because you are applying to be exempted from paying the £175 Court fee. If that is the case, then they will not be looking at the statements in relation to your bankruptcy but only to check that you do not in fact have an income greater than you are delcaring. They might query what the £200 is for but should accept your explanation if it is clear from all the other information on the statements that your income is very low.
However, that is not the end of the matter. The Official Receiver(OR) in the Insolvency Service will look into your finances in much more detail than the Court, & will question you about them. The OR may want to see your bank statements & could question you about the payment, but is likely to accept what you tell them unless they think there is something out of order in your affairs. The important thing is to be open & honest with them, & not try to pull the wool over their eyes.
