Skilled Limited works on technically difficult jobs, and as such experiences substantial “learning”. In the past, it has been very unscientific in estimating the effect of the learning, but is now keen to understand how much learning is taking place. Consequently, it has gathered some basic data: the time taken for the first 20 units of a new job was 80 hours but the next 10 units took only 30 hours and the 10 after that took 25 hours. Estimate the learning effect using all the data at your disposal.
my answer was 50%
but in the solution its given 84.375%
pls help

There is no on line support until after the 3rd of December unfortunately
Hello Amiya,
I have worked through the problem, and here is my understanding
total time taken,
First 20 units = 80 hours
next 10 units = 30 hours
final 10 units = 25 hours
thus, total time taken for first 40 units 135 hours
based on that average time per unit is,
20 units = 80/20 = 4hours
40 units = 135/40 = 3.375 hours
so the answer is,
R2 ×4=3.375
R = 0.84375
hope this clear your doubts. i planned to do exam in pm exam in December going through this help me as well.
hey iam sorry for the late reply
why arent we going with the usual method like q16 in analytical techniques . A company has started production of a new product and has found that the first 10 units of production took 120 hours. The next 30 units produced took a further 150 hours
similar to this q shldnt we have done 135=4x80r^2
135/(4x80)=r^2
=0.421875^2=64.95%
