? ​

Answer 1

Answer:

total no. of students=125

Step-by-step explanation:

let the no. of students be x

then acoording to question,

(60/100)x are female and (40/100)x are male

then acoording to next given hint,

(40/100*60/100)x are female methodology student and (70/100*40/100)x are male methodology students

then total methodology students are (40/100*60/100)x + (70/100*40/100)x

then nonmethodology students are x-(40/100*60/100)x + (70/100*40/100)x =60

after calculating we get x=125

so total no. of students is 125
