Answer 1

Let total student =x

Girls =18

A.T.Q.60% of x= 18

60/100*x=18

x=18*100/60

x=30

Total student =30

girls=18

boys=12

Answer 2

a) 3:2, b) 12:8:1, c) Rs. 78.75.

Step-by-step explanation:

Since we have given that

Let the total number of students be 'x'

40% of the total student are girls = 16

According to question, we get that

$0.4x=16\\\\x=\dfrac{16}{0.4}\\\\x=40$

So, the number of boys is given by

$40-16=24$

So, Ratio of number of boys to girls would be

$24:16\\\\=6:4\\\\=3:2$

Since 2 teachers accompany the party.

So, Ratio of number of boys, girls to teachers is given by

$24:16:2\\\\=12:8:1$

Conveyance cost = Rs. 1000

Refreshment cost = RS. 2150

total cost would be

$1000+2150=Rs.\ 3150$

Cost per head is given by

$\dfrac{3150}{40}=Rs.\ 78.75$

Hence, a) 3:2, b) 12:8:1, c) Rs. 78.75.
