Passage / Data
Answer the following question based on the information given below.
There are six companies, 1 through 6. All of these companies use six operations, A through F. The following graph shows the distribution of efforts put in by each company in these six operations.

A new technology is introduced in company 4 such that the total efforts for operations B through F get evenly distributed among these. What is the change in the percentage of effort in operation E?
Answer & solution
Reduction of 12.3
- B
Increase of 12.3
- C
Reduction of 5.6
- D
Increase of 5.6
Solution
Total of B, C, D, E and F for company 4 = 100 − 18.5 = 81.5
After introducing the new technology the value of E = 81.5/5 = 16.3
∴ The change in the value of E = 16.3 − 28.6 = −12.3
Hence, option (a).
