Question

A girl has to secure 45% marks in aggregate of three papers of 100 marks each to get through. She got 35% marks in the first paper and 50% marks in the second paper. At least how much marks should she get in third paper to pass the examination?​

Answer 1

Answer:

well First u need to assume the maximum marks as x .

so,

let maxi marks is = X.

now he fails by 30 marks so,

40% marks = (150+30)=180.

now-

X * (40/100) = 180

or, X = 180 * (100/40)

0r, X = 450

so the answer is = 450.
