# Help on SHL numerical question, just don't understand where I am wrong!

Hi folks,

I would highly appreciate if someone would help me with the following SHL question. I have attached a screen shot.

http://www.thestudentroom.co.uk/atta...1&d=1451500119

1) If all staff were required to work on assembly line A for cars, approximately how many cars would be produced a day if staff from other lines are only required to work their normal daily hours?
A.150 B.220 C.290 D.360 E.430

The answer is E (430) but I just don't seem to understand how they get this. I know that the way to calculate this is by first working out the total man hours (by multiplying the number of workers for each product with their shift hours)then dividing by 12 hours as the car assembly line requires 12 hours for a car to be produced but in my calculation I always get 395.125 and just can't seem to get 430. I have shown my calculation below . Please could someone who gets 430 please show be their working

I did (117*7.5)+(76*9)+(198*13)+(56*6)+(45*6) = 4741.5
the number of hours required to produce a car is 12 hours so 4741.5/12=395.125! I just don't get where 430 comes into the question

The key point you have missed out on in the question is "if staff from other lines are only required to work their normal daily hours". You have forgotten to include the man hours that workers would have put after the shift hours for building the other vehicles after the shift for cars is over/ hasn't started yet!

Total man hours for cars (A):

All workers must work on the cars for assembly line A during the shift period for Cars (0800-1530).

Total Workers = 117 + 76 + 198 +56 + 45 = 492
Duration of Shift Working = 7.5
Total Man Hours = 7.5*492 = 3960
Completion Time of Car = 12
Cars Produced 3960/12 = 330

The van shift period is from 0900-1800 which means that van workers will have from 1530-1800 to work on the vans as staff from other lines are required to work their normal daily hours! This means van workers will have 2.5 hours to work on vans.

Van Workers = 76
Duration of Shift Working on Vans= 2.5
Total Man Hours = 76*2.5 = 190
Completion Time of Van = 9.5
Vans Produced = 190/9.5 = 20

The LGV workers shift is from 0600-2100 which means they will have 2 hours to work on LGVs before they have to work on cars and 5.5 hours after to work on LGVs after their shift working on cars is over. They have a total of 5.5+2.5 = 7.5 hours to work on LGVs.

LGV Workers = 198
Duration of Shift Working on LGVs = 7.5
Total Man Hours = 7.5*198 = 1485
Completion Time of LGV = 22
LGVs Produced = 1485/22 = 67.5 = 67 (67.5 goes to 67 as I am assuming we are calculating the number of whole vehicles produced, this goes for other calculations too.)

The Agricultural workers shift is from 1000-1600 which means they only have 0.5 hours after the car shift is over to work on Agricultural vehicles.

Agricultural Workers = 56
Duration of shift working on agricultural vehicles = 0.5
Total Man Hours = 0.5 * 56 = 28
Completion Time of Agricultural Vehicle = 8
Agricultural vehicles produced = 28/8 = 3.5 = 3

Off-road vehicles users also have only 0.5 hours to work on off-road vehicles after the car shift is over as they have the same shift hours as the agricultural workers.

Duration of shift working on off-road vehicles = 0.5
Total Man Hours = 0.5*45 = 22.5
Completion Time of Off-Road Vehicle = 6
Off-road vehicles produced = 22.5/6 = 3.75 = 3

Now we simply add all the vehicles produced together:

330 + 20 + 67 + 3 + 3 = 423

Which is equal to "approximately" (as the question states) 430 so E is the correct answer.

I got 428.125:
(Hours * Total Workers Per Day)

7.5*117
9*76
15*198
6*56
6*45

5137.5
Divided by 12 for the man hours to make a car = 428

I did that in about 40 seconds and that's how long I would expect to spend on an SHL question?

I think 13 hours for LGV (line C) rather than 15 was your mistake? 6am - 9pm should be 15 hours rather than the 13 you used in your calculation.

I would also appreciate it if someone could help me to those 18 SHL questions. I would like to know what is the correct answer for each of them because when I had attempted them, it only tells me how many questions I got correct and how many I got incorrect but it does not tell me which ones I got correct and which ones I got incorrect and I would really like to know that.

Thanks

Hi everyone,

Are you preparing for an aptitude reasoning test?

I am one of the founders of The Aptitude Reasoning Tests Bible, which has >1,000 numerical-, logical- and verbal reasoning questions. The questions are based on real-life interviews and exams, with each question having a detailed explanation.

The app goes through all the common mistakes and how you should approach each type of question. As a bonus, the app also has commonly asked guesstimates and brain teasers with explanations so that you can impress the interviewer!

Best regards,
Jonathan Anderson
