Thank you for the opportunity to help you with your question!

moles of phosphoric acid=concentration * volume = 0.3*25=7.5mmoles

moles of NaOH=0.2mmoles

volume of NaOH = moles/concentration=7.5/0.2=37.50 mL

Please let me know if you need any clarification. I'm always happy to answer your questions.
