I didn't understand what you mean by this question

Answer 2

Explanation:

Total (incorrect) of 20 items

=20×36=720

correct terms=67+65=132

incorrect terms=47+56=103

therefore, correct total={incorrect total+correct

terms - incorrect terms}

={720+132-103}

=749

so, correct mean =correct total\ No. of terms

= 749/20

= 37.45(ans)
