Answers
Answer:
Step-by-step explanation:
for subject a he scored 73 marks out of 150 marks
which is 73/150 x 100 =49%
he scored 56% mark in subject b
the scored x mark in subject c
which is x/150 x 100 = 2x/3%
the overall percentage = (a% + b% + c%)/3=54%
= (49 + 56 + 2x/3)/3= 54%
105 + 2x/3 =54 x 3
2x/3 =162-105
2x/3 = 57
2x= 57 x 3
x= 171/2
x= 85.5%
mark he got ----- y/150 x 100 = 85.5
y = ( 85.5 x 100)/150
y = 57
