Aschool had 400 girls last year and the number of boys was 95 more than that of the girls. this year the number of girls had increased by 1/5 of last years number and is 30 more than the number of boys. by what fraction had the number of boys been reduced?

1/11

Step-by-step explanation:

The number of boys in school last year will be .

We are told that next year number of girls increased by 1/5. Next year number of girls in the school will be .

We are told that next year number of boys was 30 less than number of girls. So next year number of boys will be .

To find the factor at which number of boys reduced we will find the difference of number of boys between both years and divide by initial number of boys.

Therefore, number of boys had been reduced by 1/11.

answer: 45

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
