@zareen said in Topic 2 / Base Setting: What is Marketing?: how to understand offering? An offering in marketing is the total offer to your customers. An offering is more than the product itself and includes elements that represent additional value to your customers, such as availability, convenient delivery, technical support or quality of service. A strong offering differentiates your products from competitors and creates value by meeting customers’ wider needs better than other options.

The FIRST of a sentential form is the set of terminal symbols that lead any sentential from derived from the very first sentential form. In this particular case X and Y only derive the empty string and as a result the empty string is the FIRST set of both non-terminal symbols X and Y. The FIRST of S, however, includes “a” as in the first production once can derive a sentential form that starts with an “a” given that X can be replaced by the empty string. X similar reasoning allows you to include “b” in the FIRST(S). summary: FIRST(X) = {e}, FIRST(Y) = {e}, FIRST(S) = {a, b} The FOLLOW set of a non-terminal symbol is the set of terminals that can appear after that non-terminal symbol in any sentential form derived from the grammar’s start symbol. By definition the follow of the start symbol will automatically include the $ sign which represents the end of the input string. In this particular case by looking at the productions of S one can determine right away that the follow of X includes the terminal “a” and “b” and that the FOLLOW of Y includes the terminal “b”. Given that the non-terminal S does not appear in any productions, not even in its own productions, the FOLLOW of S is only $. summary: FOLLOW(S) = {$}, FOLLOW(X) = {a, b}, FOLLOW(Y) = {b}. b) YES, because the intersection of the FIRST for every non-terminal symbol in empty. This leads to the parsing table for this LL method as indicated below. As there is no conflict in entry then grammar is clearly LL (1).

@zaasmi said in BNK610 Grand Quiz Spring 2020: A right of a buyer to rescind a contract after an agreed time period is known as: Khiyar e Tayin Khiyar al Ruhya Khiyar e Wasf Khiyar e Aib Khiyar-e-Shart (Optional condition): At the time of sale Buyer or Seller can put a condition that he has an option to rescind the sale within the specific 4 days. This option is called Khiyar-e-Shart. Specification of the days is necessary for this Khiyar. Within this period, he has the right to rescind/dissolve the sale without any reason. If the buyer puts the condition, it is called Khiyar-e-Mushtari (option of buyer) and when put by the seller, it is called Khiyar-e-Bai (option of seller). This Khiyar is not transferred to heirs. Khiyar-e-Roiyyat (Option of inspecting goods): Where the goods can be returned after inspection. This applies automatically to all contracts. Eg. ‘A’ buys machinery from ‘B’ without seeing. However, ‘A’ has the option to return the machinery after inspection. Khiyar-e-Aib (Option of defect): Where the goods can be returned if found defective. It is the responsibility of the seller to supply goods free of error/defect or point out the defect to the buyer. No way is he allowed to cover the defect of the goods which constitutes as fraud. In one of the hadiths, Prophet has stated “He is not amongst us who indulges in fraud.” Therefore the buyer has the right to return the good in case of a defect which is considered a defect in the market and which depreciates the value of the goods. Eg. ‘A’ buys batteries from ‘B’. However, ‘A’ has the option to return them to ‘B’ if the batteries are found to be defective or not in working condition. Khiyar-e-Wasf (Option of quality): Where the goods are sold by specifying a certain quality by the Seller but which is absent in the goods. Eg. ‘A’ buys a car from ‘B’ who has specified automatic transmission of the car. However when ‘A’ uses the car, he finds the transmission to be manual. Therefore he can return the car to ‘B’ in the absence of a specific quality. Khiyar-e-Ghaban (Option of price): Where the seller sells the goods at a price which is far expensive than the market price, a Buyer has the right to return it to the seller. Eg. a Parker pen is sold to ‘A’ by ‘B’ at a price of Rs.500/-. However after the sale, ‘A’ discovers its market price to be Rs.250/-, he has the option to return the pen to ‘B’. Iqala (Recession of Contract): Where parties freely consent to rescind the contract i.e. each party will give back the consideration received by it. Neither the buyer nor the seller has the sole right to rescind the contract after execution of a contract. Often the buyer wants to rescind the contract after buying goods. In this case, it is necessary that he gets the seller’s consent. Therefore this mutual agreement between buyer and seller to rescind the contract is called Iqala. In one of the hadiths, Prophet has stated “He who does the Iqala (rescinding of the contract) with a Muslim who is not happy with his transaction, Allah will forgive his sins on the Day of Judgment.” However, it may be noted that the price of the goods being returned under Iqala will remain unchanged. Effect on third Parties: Iqala is treated as a new sale as if a new contract is entered into between the parties rescinding the original contract.
