Answer 1

Answer:

76% mark me as brainilest

Step-by-step explanation:

Let there be 100 students.

Then number of boys =53×100=60

Number of girls =52×100=40

Total scholarship holders =20 % of 60 + 30 % of 40= 10020×60+10030×40 = 12+12=24

Number of students without scholarship =100−24=76

∴% of students without scholarship =10076×100=76 %
