(a) For: Yes, vestibule training is better than on-the-job training, because: 

1. This training method helps the trainees to overcome initial nervousness before working on the actual job. Trainees get accustomed to the work routine whereas, on-the-job training method gets difficult for the trainees because in the course of training, employees may cause damage to expensive equipments and rate of accidents may increase. 

2. Vestibule training helps the trainees to get specialised in their skills under expert trainers and special instructors. 

(b) Against: Skimming pricing policy is not ideal for introducing a product in the FMCG sector, because: 

1. In FMCG sector, the goods are sold at a low price for quick sales, but in skimming pricing, the initial price of the goods are very high. 

2. In FMCG sector, the aim is not to ‘sell to classes’ who don’t care how much they pay for a novel product, but the price strategy, skimming pricing strategy follows this aim which is not ideal for any product to be introduced in FMCG sector. 

(c) Against: Rather closing stock is valued at market price or at cost, whichever is less. This rule is based on the principle of conservatism which states that probably losses are taken into account, but not the probable gains. It is also necessary to be careful while valuing closing stock correctly. Otherwise gross profit, thus ascertained, would not be correct one. 

(d) For: Yes, all membership fees collected by a non-trading concern should not be entered in the asset side of the Balance Sheet because: 

1. This is an income reported in the income and expenditure account. 

2. This is a revenue income but not a capital income. 

(e) For: Yes, abnormal costs are not recorded as a part of production costs, because: 

1. It is cost which is not normally incurred at a given level of output in the conditions in which that level of output is normally attained. 

2. Abnormal cost is charged to profit and loss account.
