Let the number of students be 100.

Given:

65 students are boys. It means 35 students are girls.

And,

80% of girl students were present.

=> 80% of 35

=> (80/100) * 35

=> 28.

Now,

Total number of students present that day was 70%.

=> 70 - 28

=> 42

Then:

Fraction of boys present:

= (42/65) * 100

= (4200/65)

= 64.6%

Hope it helps!
