In a particular year, the number of students enrolled in different streams in a College is as follows:

The percentage of girls students is:

46%

Total number of students = Total number of girls + Total number of boys

= ( 32 + 28 + 42 + 13 ) + ( 18 + 45 + 42 + 30 )

= 250

Total number of girls = 32 + 28 + 42 + 13 = 115

Percentage of girls students = \(\frac{115}{250}\) × 100

= 46%
