(C) Let the total number of students who appeared for the test be $y$.The number of male students who appeared $= 0.9y$.The number of female students who appeared $= 0.1y$.According to the problem,$60 \%$ of males and $80 \%$ of females passed the test.Passed males $= 0.60 	imes 0.9y = 0.54y$.Passed females $= 0.80 	imes 0.1y = 0.08y$.Total passed candidates $= 0.54y + 0.08y = 0.62y$.Given that the total number of passed candidates is $1240$,we have:$0.62y = 1240$$y = \frac{1240}{0.62} = \frac{124000}{62} = 2000$.Therefore,the total number of candidates who appeared for the test is $2000$.
