The following table shows the number of employees working in four colleges A to D, split into males, females, teaching males, teaching females, non-teaching males and non-teaching females. Some values are missing and are to be calculated if required. Known figures: College A has 756 employees, 526 males and 325 teaching males; College B has 159 teaching females, 215 non-teaching males and 254 non-teaching females; College C has 159 males; College D has 224 employees, 142 males and 82 females. Based on the data, answer the questions that follow.
In College D, if the number of teaching females and non-teaching females are equal, and the number of teaching males is 5 more than the number of teaching females, then the difference between non-teaching males and non-teaching females is
A224
B102
C55 ✓ Correct
D79
Correct answer: (C) 55 — The difference is 55, so the answer is 55.
Explanation
★The difference is 55, so the answer is 55.
★College D has 82 females, split equally into teaching and non-teaching females.
★Let each be x, so x plus x equals 82, giving x equal to 41.
★So teaching females and non-teaching females are 41 each.
★Teaching males are 5 more than teaching females, which is 46.
★College D has 142 males, so non-teaching males are 142 minus 46, which is 96.
★The difference is 96 minus 41, which is 55.
