Explanation
Mark-up is the amount added to the cost of an item to get to its selling price and is expressed as a percentage.
Mark-up(%) = (Price - Cost) / Cost x 100
= (100 - 9 - 51 - 24) / (9 +51 +24) x 100 = 16 / 84 x 100 = 19.04%

Explanation
In order to answer this question, you should better consider each option:
'Exchange rate' is the value of one nation's currency versus thecurrency of another nation or economic zone.
This is a macroeconomic factor.
'Elasticity' refers to the degree to which individuals, consumers or producers change their demand or the amount supplied in response to price or income changes. This is a microeconomic factor Consumer tastes refer to the products and services that consumers consciously choose over others. Consumer tastes are so powerful that they can change how businesses conduct their activity. Like elasticity, this is also a microeconomic factor.
Among 4 options, only risk management is the internal factor. Risk pricing is a strategy applied by many companies in the world. To learn how to price the risk, you can read an article from McKinsey:

In the scenario, the manager propose to 'split the difference', which means each party will accept some of their demands and concede some. This is known as 'Compromise'.

Explanation
A perfectly competitive market is one with the following features:
- There are many firms producing identical or very similar (homogeneous) goods or services
- There are no barriers toentry to the market or exit from the market - anyone can enter or leave easily
- Both producers and customers have perfect knowledge of the market place, prices, costs of production and influences on demand and supply Under these conditions, the price andquantity will always tend toward equilibrium as any producer that sets a price above equilibrium will not sell anything at all, and any producer that sets a price below a equilibrium will obtain 100% market share in theory. The demand curve is perfectly elastic, which means that it will be horizontal. In a perfectly competitive market, it is difficult to increase profits through pricing, and suppliers instead must focus on their cost structure. As these conditions imply, there are few if any examples of perfectly competitive market.

In the study guide, CIPS lists 5 stages of an negotiation:
The opening phase: confirm understanding and get the issues on the table. At this stage, both parties should check agenda, authority and create atmosphere conducive to agreement The testing phase is an information gathering stage where the hypothesis and assumptions you have made in the planning stage can be tested and confirmed or disconfirmed The proposing phase: Both sides may start making tentative proposals regarding their offering.
The bargaining phase: Both parties trade concessions; the preliminary stages are over and proposals move from being tentative and general to being more definite and specific.
The agreement and closing phase: both parties should seek agreement or if TOP does not have the final authority, some sort of acknowledgement of what key terms are should be sought.
