spoorthy  (9 years ago)

total no.of candidates=120 and avg is 35
then total marks obtained by total candidates will be=120*35(hint:total/num=average)
let us consider passed candidates will be x
failed candidates will be120-x
so

120*35=x*39+(120-x)15

By solving the equation we will get x=100

So ans:100

the total marks obtained by 120 candidates=4200
let the total marks by passed candidates=x

4200=39x+1800-15x
4200=24x+1800
x=100
