NPV real coc/nominal coc

Came across a question (section c), it had different inflation for sales, v.c and f.c, they also gave us a general inflation rate, gave both money cost of capital and real cost of capital, clear my confusion on this because i thought regarding real rate we dont inflate cashflows and outflows, but in the answer (they required both npvs, using nominal and real c.o.c) the did nominal npv using the specifc inflation rates and for real npv they used general inflation rate to inflate cashflows and outflows.
