Number of boys = 142

Number of girls = 300 – 142 = 158

In a school, number of teachers are = 30

Number of male teachers are = 12

Number of female teachers are = 30 – 12 = 18

Total number of students and teachers is = 300+30 = 330

Total numbers of female in the school is = 158+18 = 176

Percentage of female in the school = (176/330) × 100

= 160/3%

∴ Total of 160/3% are female in the school.

"hello students i am vita your math leader tutor and today's question is a certain school has 300 students 142 of whom are boys it has 30 teachers 12 of whom are man what percent or the total number of students and teachers in the school is female so in this question first of all the total students is equal to total students is equal to 300 142 of whom are boys so the number of female students number of female students is equal to 300 minus 142 then we get 300 minus 142 10 minus 2 8 9 minus 4 5 and 2 minus 1 1 it is 1 58 affiliate students and total teachers total teachers is equal to 30 and number of female teachers number of female teaches is equal to 30 minus 12 so it becomes 18 now the total number of total number of females are 158 plus 18 so it becomes 176 and the total number of the students and total number of total number of students and teachers students and teachers is equal to 300 plus 30 is equal to 330. now we have to find the percentage of females is equal to number of female to the number of females 170 6 176 divided by total number of students and teachers are 330 into 100 cancel out each other eleven threes are eleven and eleven six so it becomes one sixty by 3 percent so this is our answer i hope you like this video so please subscribe for more updates and do comment your questions thank you"
