Question

Given below are the runs scored by five players. If the average runs scored by them is $146$, then find the runs scored by Kuldeep.​ Name Runs

Rahul	$144$
Suresh	$155$
Amar	$126$
Khalid	$136$
Kuldeep	$?$

• A. $155$
• B. $321$
• C. $149$
• D. $169$

Answer 1

The correct option is D $169$

Let the runs scored by Kuldeep be $k$.​
Total runs scored by all the players $=144+155+126+136$$+k=561+k$
Average runs scored $=146=\frac{\text{Total runs scored}}{\text{Number of players}}$

$⟹146=\frac{(561+k)}{5}$
$730=561+k$
$k=730-561=169$
Therefore, Kuldeep scored $169$ runs.
