Have a doubt on the LR question regarding apps. One of the conditions in the question says:
"He will install Calendar, if and only if he installs Run Run. "
Isn't it supposed to mean: Calendar will be installed only if there is Run Run, in other words there is a choice to install Calendar if there is Run Run.
But the solution says 'If he installs Run Run, he has to install Calendar'.
Please let me know in case I am wrong.
