Answer 1

Step-by-step explanation:

Let the total no.of students be x

if the no of boys is 840 and % of boys is 60%

so 60% of x = 840

60x= 840×100

x = 84000/60

x = 1400

total student in school= 1400

no.of girls = total no.of students - no.of boys

1400-840

=560 girl

Answer 2

Answer:

total students = 840

number of girls = 7

number of boys = 840 - 7 = 833

number of girls = 7

number of boys = 833

there are 840 students in total and 7 are girls in the school so you have to find the number of boys so if the number of girls are 7 so total students are 840 so 8:40 -7 is equal to 833 is the answer
