Answer:-

• 75

Let the number of geography be 'X'

As per the question,the average number in 6 subjects is:- 65.

Given:-

Marks in English=64

Marks in Hindi=68

Marks in Maths=58

Marks in Science=55

Marks in History=70

So, Marks in Geography=?

As per the question,

\frac{64+68+58+55+70+X}{6}=65

\implies\frac{315+X}{6}=65

\implies\:315+X =6\times 65

\implies\:315+X =390

\implies\: X =390-315

\implies\:X =75
