(Question:88677.0)

Question:

Akash scored 73 marks in subject A. He scored 56% marks in subject B and X marks in subject C. Maximum marks in each subject were 150. The overall percentage marks obtained by Akash in all the three subjects together was 54%. How many marks did he score in subject C?

Options:
A) 84
B) 86
C) 79
D) 73
Solution:

Ans: (b)

Mark for subject A=73

Mark for subject B=56% of 150 =150\(\times\)56 / 100 =84

Mark for subject C=\(x\)


Now  overall percentage marks = 54%


so 

(73 + 84 +\(x\) ) /450 \(\times\)100  =54

=>(73 + 84 +\(x\) )=243

=>73 + 84 +\(x\)=243

=> 157+\(x\)=243

=>\(x\)=243-157

=>\(x\)=86
