GUYS 50 POINTS ENJOY BUT PLZ GIVE THE CURRECT ANSWER . A school conducts three exams namely term1, term 2 and final-term exams. Final marks scored (weighed marks) are computed as 30% of term1 + 30% of term 2 + 40% of the final-term 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 (final) term. Then compute the weighted percentage out of 500 marks.
Answers
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 :
\frac{412 \times 100}{500} = 82.4\%500412×100=82.4%
In second term number got : 423 out of 500.
So, % number in second term :
\frac{423\times 100}{500} = 84.6\%500423×100=84.6%
In third term number got : 430 out of 500.
So,% number in third term :
\frac{430 \times 100}{500} = 86\%500430×100=86%
Weightage of first term = 30 %
So, % weightage got in first term :
\frac{82.4 \times 30}{100} = 24.72\%10082.4×30=24.72%
Weightage of second term = 30 %
So, % weightage got in second term :
\frac{84.6\times 30}{100} =25.38\%10084.6×30=25.38%
Weightage of third term = 40 %
So, % weightage got in third term :
\frac{86 \times 40}{100} = 34.4\%10086×40=34.4%
Total weightage percentage of three exams :
(24.72 + 25.38 + 34.4 )% = 84.50 %
Answer:
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 :
\frac{412 \times 100}{500} = 82.4\%
500
412×100
=82.4%
In second term number got : 423 out of 500.
So, % number in second term :
\frac{423\times 100}{500} = 84.6\%
500
423×100
=84.6%
In third term number got : 430 out of 500.
So,% number in third term :
\frac{430 \times 100}{500} = 86\%
500
430×100
=86%
Weightage of first term = 30 %
So, % weightage got in first term :
\frac{82.4 \times 30}{100} = 24.72\%
100
82.4×30
=24.72%
Weightage of second term = 30 %
So, % weightage got in second term :
\frac{84.6\times 30}{100} =25.38\%
100
84.6×30
=25.38%
Weightage of third term = 40 %
So, % weightage got in third term :
\frac{86 \times 40}{100} = 34.4\%
100
86×40
=34.4%
Total weightage percentage of three exams :
(24.72 + 25.38 + 34.4 )% = 84.50 %
