The marks obtained by a student of class XI in first and second terminal examination are 62 and 48, respectively. Find the minimum marks he should get in the annual examination to have an average of at least 60 marks.

Answer»

Let x denote the mark obtained by the student in Class XI examination, then;

 \(\frac{62+48+x}{3}\) ≥ 60 

⇒ 110 + x ≥ 1800 

⇒ x ≥ 70.
