In a sales analytics exercise, NESCAFE 3-in-1 baseline weekly sales are 1,500 cases. A digital promo boosts sales by 40% in the first week. The second week, sales drop by 15% from that elevated level, and the third week returns to baseline. How many total cases are sold over the three weeks?
Why This Is Asked
This evaluates numerical reasoning and attention to detail, which are important for data-driven decision-making in both Commercial and Supply Chain tracks.
General Approach
Practice percentage change problems with multiple steps before the assessment. When answering, clearly state each weekly calculation and then sum, rather than trying to combine steps into one mental leap.
Sample STAR Answer▾
Situation
I was taking the online cognitive assessment for the Management Trainee program, and this data interpretation problem appeared with a 2-minute timer.
Task
I had to read the scenario carefully, calculate each week's sales correctly, and sum them up.
Action
I first calculated Week 1: 1,500 times 1.40 equals 2,100 cases. Then Week 2: the drop is 15% from the boosted level, so 2,100 times 0.85 equals 1,785 cases. Week 3 is baseline 1,500 cases. I added them: 2,100 plus 1,785 plus 1,500 equals 5,385 cases total. I double-checked my multiplication and addition before clicking submit.
Result
I got the answer correct and finished with a few seconds to spare, which contributed to progressing to the next round.
