At a certain factory, the number of first-shift workers is 2/3 the number of second-shift workers. Every day, each second-shift worker can make 4/3 as many light bulbs as each first-shift worker.
In the first column, identify a possible number of total light bulbs made on one day by the two shifts combined; in the second column, identify the corresponding number of total light bulbs that the first-shift workers made on the same day. Make only two selections, one in each column.
  • a)
    Total Bulbs for Both Shifts: 36
    Total First-Shift Bulbs: 12
  • b)
    Total Bulbs for Both Shifts: 3
    Total First-Shift Bulbs: 6
  • c)
    Total Bulbs for Both Shifts: 12
    Total First-Shift Bulbs: 6
  • d)
    Total Bulbs for Both Shifts: 12
    Total First-Shift Bulbs: 24

Let number of second shift workers be n
Then number of first shift workers = 2n/3
Let b the number of bulbs made by each worker in the first shift
Then number of bulbs made by each worker in the second shift is 4b/3
Total bulbs made by first shift workers: 2nb/3
Tota bulbs made by second shift workers: 4nb/3
Total bulbs by both: 6nb/3 => 2nb
Now try substituting value of 2nb (first column) to find nb and get 2nb/3 (second column)
If 2nb =3, nb. = 3/2 not possible => eliminate
If 2nb = 6, nb = 3 => 2/3 nb = 2 which is not present => eliminate
If 2nb = 12, nb = 6 => 2/3 nb = 4, again not present => eliminate
If 2nb = 24, nb = 12 => 2/3nb = 8, again not present => eliminate
Therefore only 36 should fit in. Let's check
2nb = 36 => nb = 18 => 2/3nb = 12
Hence Total Bulbs for Both Shifts (Column 1) = 36
Total First-Shift Bulbs (Column 2) = 12
