- Question 1: Attilla offered to sell her luxurious handbag to Aisyah for RM 50,000 through a letter. Aisyah in reply gave a new figure of RM 40,000. Attilla kept silent and did not reply the said letter. After one week, Aisyah changed her mind and agreed to the original price of RM 50,000. Attilla refused to sell because she has already made a promise to sell her handbag to Farah for RM 66,000. Advise whether Attilla can be held liable for breach of contract.Get Answer
