I am new to this forum and would really appreciate if you guys could advise me on this case study of my current contract law.
Below are the scenario,
Naiker has recently developed an interest in playing the piano. He wanted to buy
a second hand piano to learn. Ahmad who owned a piano posted an offer by
letter to Naiker on Monday 2 June as follows:
“Good quality piano for sale $ 2,500. If you are interested in buying you must
write to me.”
The letter Ahmad posted was delayed because of the postal strike and only
reached Naiker on Thursday 5 June. When Naiker saw this offer he was
overjoyed and in order not to miss the opportunity of buying the piano he
immediately posted his letter of acceptance on Friday 6 June. Naiker’s letter only
reached Ahmad on Monday 9 June.
Meanwhile, Ahmad not receiving a reply from Naiker believed that he is no longer
interested in buying the piano, sold it to Janice on Friday 7 June.
Since Ahmad is an accomplished pianist he organises concerts and plays the
piano in these concerts. As usual he had booked the Emerald Concert Hall for
his concert.
But just one day before the concert Emerald Concert Hall was struck
by lightning and the entire concert hall was burnt down. Ahmad had to cancel the
concert and refund all the money paid by the audience. His piano which was
brought to the Emerald Concert hall two days before the concert has also been
destroyed by the fire.
A) Advise Naiker whether there is an enforceable contract?
B) Advise Ahmad whether he has any claim against Emerald Concert Hall in
contract law?
And this report has to be at least 1600 words!

Super much appreciated if you could help me out on this!
THANK YOU!!
