DAT and OAT Math Practice Question (From Our Math Instructor)
Max and Dave received a combined test score of 140. Max’s score was Z times higher than Dave’s.
How much did Dave score in terms of Z?
A) 140/(Z+1)
B) 140/(Z−1)
C) Z/(140+1)
D) 1/(140+Z)
E) Z/(1−140)
Solution
Let:
- M = Max’s score
- D = Dave’s score
We are told:
M = Z·D
Their combined score is:
M + D = 140
Substitute:
Z·D + D = 140
D(Z + 1) = 140
D = 140/(Z + 1)
✅ Correct Answer: A
