NCHMCT JEE 2020 Question Paper with solutions for online practice

Given, the mean of 11 numbers $=35$
$\therefore$ Sum of 11 numbers $=35\times 11=385$
Now, mean of first 6 numbers $=32$
$\therefore$ Sum of first 6 numbers $=32\times 6=192$
Similarly, sum of last 6 numbers $=37\times 6=222$
Hence, sixth number $=\left[222+192\right]-385$
$=414-385=29$
