If an aircraft has three components which can be considered as vulnerable components then, evaluate total vulnerable area. Given area of component 1, 2 and 3 are 5ft2, 4ft2 and 80ft2 respectively with Pk as 1, 0.5 and 0.3 for component 1, 2 and 3 respectively.

If an aircraft has three components which can be considered as vulnerable components then, evaluate total vulnerable area. Given area of component 1, 2 and 3 are 5ft2, 4ft2 and 80ft2 respectively with Pk as 1, 0.5 and 0.3 for component 1, 2 and 3 respectively. Correct Answer 31ft2

Given, part 1: area a1=5ft2, pk1=1 Part 2: area a2=4ft2, pk2=0.5 Part 2: area a3=80ft2, pk3=0.3 Total vulnerable area = a1*pk1 + a2*pk2 + a3*pk3 = 5*1 + 4*0.5 + 80*0.3 = 5+2+24 = 31ft2.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?
Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Two person X and Y together can make 25% of total number of bricks in 4.8 days.

You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
