Hi,
Could you please help me with MCQ 39.3 from BPP revision kit?
“A company began producing a new product in batches four months ago. When production commenced the first batch took 45 hours.
1month – 1 batch
2month – 2 batches – 75% learning rate
3month – 4 batches – 75% learning rate
4 month – 8 batches – 90% learning rate
What was the average production time per batch for the first eight batches?”
Thank youI think you have misread the question (because you have typed it wrongly).
The production is not 2 batches in month 2, 4 batches in month 3.
In month 2 the total to date is 2 batches (so they only made 1 batch in month 2).
In month 3, the total to date is 4 batches (so they only made 2 batched in month 3)
And similarly the only made 4 batches in month 4.The average time when making 1 is 45 hours.
The average time when making 2 in total is 45 x 0.75 =33.75 per batch
The average time when making 4 in total is 33.75 x 0.75 = 25.1325 per batch
The average time when making 8 in total is 25.1325 x 0.9 = 22.78125 per batch.
