During a pre-calculus placement test, I came across the following question under Matrix and Determinants Section:
The number of PMU students taking Calculus I for the next semester is supposed to
be 127 . The number of males will be one more than 4/3 of the females. How many
female students will be enrolled in Calculus I ?
(A) 53 (B) 54 (C) 52 (D) 55
Of course I couldn't answer it as it was too difficult to me specially it's been long time since I studied calculus during high schools times.
When I got home, Ithought about having it here in the forum so that anybody can help.
