b) 3:2
c) 4.5
d) none of these​

Answer 1

Answer:

Ratio of Girls to boys = 3 : 2

Step-by-step explanation:

Girls are 60% of the total number of students and are 18 in number.

Let say total students = T

Girls = (60/100)T

=> 18 = 3T/5

=> T = 30

Boys = 30 - 18  = 12

Ratio of Girls to boys = 18 : 12

=> 3 : 2

Transportation cost  = 55 * 12  = 660 Rs

Refreshment Cost = 4280 Rs

Total Cost = 660 + 4280  =   4940 Rs

Total number of Heads = 30 Students + 2 Teachers = 32 Teachers

Cost Per Head = 4940/32 = 154.375 Rs

(22/55) * 100 = 40%

Distance left = 100% - 40% = 60%
