Answer:
<h2><em><u>61 marks</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
Marks of the four exams = 65, 80, 76, 68
Let the mark for the fifth exam be = x
Mean of the five exams = 70
<em><u>Therefore</u></em><em><u>,</u></em>
<em>By</em><em> </em><em>the</em><em> </em><em>problem</em><em>, </em>
=> 289 + x = 70 × 5
=> 289 + x = 350
=> x = 350 - 289
=> x = 61
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Marks</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>fifth</u></em><em><u> </u></em><em><u>exam</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>61</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
