<p>Total students = 1000 Let, students appear in exam Z only = a Total students appeared in exam Y = 360 Ratio of number of students appeared in exam X and Y only to students appeared in exam Y and Z only = 2 : 3 Students appeared in exam X and Z both = a/2</p>

<p>Number of students appeared in all three exams = 4/100 × 1000 = 40</p>

<p>Number of students appeared in Y exam only = No. of students appeared in Y and Z only = 3x</p>

<p>Number of students appeared in exam X and Y only</p>

<p>= 2/3 × 3ð&#157;&#145;¥ = 2X</p>

<p>1000</p>

<p><img loading="lazy" alt="" src="https://hranker.com/admin/assets/uploads/ckeditor/deepaksharma_14.01.2022_D3.png"></p>

<p>Now, 2x + 3x + 3x + 40 = 360</p>

<p>⇒ x = 40</p>

<p>and, 12.5x + a + a/2 + a = 1000</p>

<p>5a/2 = 500</p>

<p>⇒ a = 200</p>

<p>1000</p>

<p><img loading="lazy" alt="" src="https://hranker.com/admin/assets/uploads/ckeditor/deepaksharma_14.01.2022_D4.png"></p>

<p>Student not appeared in exam Y = 1000 – 360 =</p>
