Question

in an examination 6000 candidates appeared of whom 15% where girls and the rest were boys if 5% of the boys and 15% of the girls failed what percentage of the candidate passed

Answer 1

girls=15*6000/100=900

boys=6000-900=5100

failed=5%boys+15%girls

=(5*5100/100)+(15*900/100)

=255+135

=390

%of candidate failed=390*100/6000=39/6=6.5%
