Question

A school conducts three exams namely term1 exams, term2 exams and
final term exams. Final marks scored (weighted marks) are computed as
30% of term1 and term2 each’s marks +40% of the final marks. Write a
program to compute the weighted marks for a student who scored 412 in
first term, 423 in second term and 430 in third term. Then compute the
weighted percentage out of 500 marks.

Answer 1

Answer: In C++

#include<iostream>

int main()

{

int a,b,c;

float total,percentage;

std::cin>>a>>b>>c;

total=(a*0.3)+(b*0.3)+(c*0.4);

percentage=(total*100/500);

std::cout<<percentage;

}

Explanation:

total marks=(412*30/100)+(423*30/100)+(430*40/100)

                  =422.5

percentage=total*100/500

                   =84.5
