Answer:

120

Step-by-step explanation:

let the total girls be X

3/ 4 * X travel to school by bus

3/4 X travel to school by bus

remaining girls = X - 3/4 X

= X / 4

given 12 girls don't come to school by bus

X /4 = 12

X = 12* 4 = 48

total girls are 48

ratio of total students to boys 5:3

total students = 5 x

total boys = 3 X

total girls = 48

48+ 3x = 5 x

48= 5 x - 3 X

48 = 2 X

X = 48/2

X = 24

total boys = 3 X = 3 * 24= 72

total girls = 48

total students = 5 x = 5*24 = 120
