B	75	65	85	75	75	70
C	80	80	70	60	70	60

Find the percentage scored by C.

Correct option is B

Given:

Maximum marks = 100

Total subjects =6

Marks obtained

English =80, Hindi = 80 , Maths =70 , Physics =60, Chemistry =70, Biology =60

Formula Used:

Percentage =$$\frac{\text{Value}}{\text{Total value }}\times 100\%$$

Solution:

Total marks= 100 +100 +100 +100 +100 +100=600

Marks obtained = 80 +80 +70 +60 + 70 +60 = 420 

Percentage scored by C =$$\frac{420}{600} \times 100 =70\%$$

Thus, Option (b) is right.
