<p>Welcome to today’s tutorial on <strong>NECO Mathematics past questions</strong>.<br>In this lesson, we will solve a <strong>statistics question</strong> involving the calculation of <strong>mean scores and the total number of students</strong>. This concept frequently appears in <strong> May/June examinations</strong> and is essential for students preparing for senior secondary certificate exams.</p>

<p><strong>Problem:</strong></p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Twenty girls and <strong>Y boys</strong> sat for an examination.<br>The mean score obtained by the girls was <strong>52</strong>, and the mean score obtained by the boys was <strong>57</strong>.<br>The total score of both the girls and boys combined was <strong>2750</strong>.</p>
