Required Answer:

CLS

INPUT "ENTER MARK OF SUBJECT 1";A

INPUT "ENTER MARK OF SUBJECT 2";B

INPUT "ENTER MARK OF SUBJECT 3";C

TOTAL=A+B+C

PERCENTAGE=(TOTAL/300)*100

PRINT "TOTAL-";TOTAL

PRINT "PERCENTAGE-"; PERCENTAGE

END

Logic:-

• Accept marks of 3 subjects (say, A,B,C)
• Calculate the total = A+B+C
• Calculate percentage marks = (total/300)*100
• Display the total and the percentage marks

Note:-

• You can also write PERCENTAGE=(TOTAL /3) as 100/300=1/3
