NCHMCT JEE 2021 Question Paper with solutions for online practice

$\because$ Average score of runs of 11 innings $=63$
$\therefore$ Total score of runs of 11 innings $=11\times 63=693$
$\because$ Average score of runs of first 6 innings $=60$
$\therefore$ Total score of runs 6 innings $=6\times 60=360$
Now, average score of runs of last 6 innings $=65$
$\therefore$ Total score of runs of last 6 innings $=6\times 65=390$
Hence, total runs scored in sixth innings
$=360+390-693=750-693=57$
