Marks scored by students in three mock tests (out of 100) are given below. Find out who performed the best.​ Name Test 1 Test 2 Test 3 Alex Bob Sam Rick

$88$	$74$	$56$
$65$	$61$	$80$
$69$	$74$	$91$
$72$	$90$	$84$

• A. Alex
• B. Sam
• C. Bob
• D. Rick

Answer 1

The correct option is D Rick

To find out who performed the best, we need to find the average score of each of the students in all the three tests.

Alex’s average score $=(88+74+56)/3=72.6$
Bob’s average score $=(65+61+80)/3=68.66$
Sam’s average score $=(69+74+91)/3=78$
Rick’s average score $=(72+90+84)/3=82$

By comparing the average scores, we can say that Rick performed the best with an average score of $82$.​
