A/B ==2/5,
B/C ==5/3,
A+B+C==60, solve for A, B, C
A==12 kg,  B==30 kg,  C==18 kg
Grade B==7/kg
Grade A==7/kg - 2==5/kg
Grade C==7/kg + 3==10/kg
B==7/kg x 30 kg==210 - Grade B pears
A==5/kg x 12 kg ==60 - Grade A pears
C==10/kg x 18 kg==180 Grade C pears
So: A : B : C ==60 : 210: 180==2 : 7 : 6 [Their ratio by the number of pears in all 3 grades]

How to do that

A four-dimensional cube has 24=16 corners and 2⋅4=8 three-dimensional sides and 24 two-dimensional faces and 32 on-dimensional edges.

We have to crate a ratio table

7 people

Start with $160. and subtract $12 for parking because you have to pay that no matter how many people you buy tickets for.

160-12=148

Now you can see how many tickets you can buy with $148 by dividing by the price of the ticket which is $20.50

148/20.5=7.21951219512

You can buy 7 tickets

if you do the math, there is $4.50 leftover

1 hour=60 minutes

2:20 to 3:20=60 minutes 

3:14=60-6=54 minutes
