Rini lost her Persian cat, Bobo. She advertised in the newspaper a reward of RM 500 to anyone who can find and return the Bobo to her. Farah, her neighbor, found Bobo trapped in a drain. She knew that the cat belonged to Rini, so she returned it to her. Farah only knew of the reward the next day after reading the advertisement. Farah wishes to claim the RM 500 from Rini.

Advise farah.
