Show answer & explanation
Correct answer: B
Concept: When a cost schedule quotes a rate per employee per month, the actual cost incurred in a stage equals the sum, over every month in that stage's month-range, of (rate multiplied by the number of employees working that month) - not simply rate multiplied by the number of months. The stage with the largest such sum is the costliest one.
Applying this to the given schedule, using the cost-rate table and the month-wise employee counts:
Stage | Months | Rate (Rs '000 per employee per month) | Employees each month | Total cost (Rs '000) |
|---|---|---|---|---|
Specification | 1-2 | 40 | 2, 3 | 80 + 120 = 200 |
Design | 3-4 | 20 | 4, 3 | 80 + 60 = 140 |
Coding | 5-8 | 10 | 4, 5, 5, 4 | 40 + 50 + 50 + 40 = 180 |
Testing | 9-10 | 15 | 4, 1 | 60 + 15 = 75 |
Maintenance | 11-15 | 10 | 3, 3, 1, 1, 1 | 30 + 30 + 10 + 10 + 10 = 90 |
Cross-check for Specification: since the rate stays constant across its two months, the total can also be found by first adding the employees (2 + 3 = 5) and then multiplying by the rate (5 x Rs 40,000 = Rs 2,00,000) - the same figure, confirming the month-by-month sum.
Comparing all five totals, Specification's Rs 2,00,000 is the highest of every stage, making Specification the most expensive stage under this technique.
