Answer 1

score in c = 86 take a look at picture.
total obtained marks 450×54/100= 243
so A+B+C= 243
So C= 243- (73+ 56×150/100) = 243- 157= 86

Answer 2

Answer:

86

Step-by-step explanation:

Maximum marks in each subject = 150

Maximum marks in total = 150+150+150 =450

Marks in Subject A = 73

Marks in Subject B = 56% =$\frac{56}{100}\times 150 =84$

Let the marks in Subject C be x

The overall percentage marks obtained by Akash in all the three subjects were 54%

Total Obtained Marks = $54% \times 450 =\frac{54}{100}\times 450=243$

So, Total marks = $73+84+x=243$

Solving for x

$73+84+x=243$

$157+x=243$

$x=243-157$

$x=86$

Hence he scored 86 marks in Subject C.
