Hello, I'm working through Bostock & Chandler's 'Further Pure Mathematics'. Question (4, p491/492) has been fine besides part (f), I've given it about 3 tries with slightly different approaches, I can show <SNP = <NPS and for V to lie on MP (V between M and P), <SPV=<SPM=<NSP which doesn't work (for me). I know that <NPS=<NPV (MP produced to V, right of P) due to optical properties, so should <SPV be read as <NPV instead? I'm hoping for a misprint. Many thanks for any help given.

You're right, it must be a misprint.
