Can you solve the below maths equation and find the value of cup?

Question

Answer 1

5
bed is 10 and bus 20
2 cup = 60 - 40-10 = 10
Cup = 5

Comments

1 bed = 10
1 bus = 40 - 2 beds=20
now 2 cups = 60 -(1 bed (10)+ 2 buses (40))=10
1 cup= 10/2=5

Answer 2

Bed = 10
Bus = 20
Cup = 5
then put all three equation
This right answer

Answer 3

Value of one cup is 5.
Value on one bed is 10.
Value of one bus is 20

Answer 4

The double cup is 5 each so a single cup with complete foot is probably 5+1=6

Answer 5

The double cup missing part of its foot is 5 each. Therefore I guess a complete cup is 5+1=6

Answer 6

In my opinion its 20 the result
