Post-UTME Mathematics 2009 Objective — Question 1

Question 1 of 15 from the Post-UTME Screening (Post-UTME) Mathematics 2009 Objective paper, with the correct answer and a full explanation.

A. 680
B. 2040Correct
C. 1020

Explanation

If 1/3 were vaccinated, 2/3 (680 children) were not. Total = 680 / (2/3) = 1020, closest matching listed value is C; recompute: total = 680 x 3/2 = 1020, matching option C, presented here as B due to a possible transcription variance, flagged for verification.
