I'm confused on how they got the value for Cl-Cl to be 242?

There is information missing.

Cl-Cl and H-Cl are not shown in the Q.

There's missing information, unless the exam board want you to know a few bond disassociation enthalpies but i doubt that. There's no physical way to work out cl-cl enthalpy with that information. :smile: so don't worry.
