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(write a java program using scanner class).

Answer 1

Answer

Given :

Marks got in 1st,2nd and 3rd term : 412,423 and 430 out of 500.

Weightage of 1st,2nd and 3rd term : 30%,30% and 40%

To find :

Weightage percentage.

Solution :

In first term number got : 412 out of 500.

So, % number in first term :

412×100/500 = 82.4%

In second term number got : 423 out of 500.

So, % number in second term :

423×100/500 = 84.6%

In third term number got : 430 out of 500.

So,% number in third term :

430×100/500 = 86%

Weightage of first term = 30 %

So, % weightage got in first term :

82.4×30/100= 24.72%

Weightage of second term = 30 %

So, % weightage got in second term :

84.6×30/100= 25.38%

Weightage of third term = 40 %

So, % weightage got in third term :

86×40/100= 34.4%

Total weightage percentage of three exams :

Total weightage percentage of three exams :(24.72 + 25.38 + 34.4 )% = 84.50 %
