Question

3 chairs = 30
1 chair + 1 umbrella = 40
1 chair + 1 umbrella +1 cone = 60
What is equal to 1 cone ?

Answer 1

Answer:

20

Step-by-step explanation:

3 chairs = 30

So 1 chair = 30/3 = 10

1 chair + 1 umbrella = 40

So 1 umbrella = 40-10 = 30

1 chair + 1 umbrella + 1 cone = 60

So 1 cone = 60 - 40 = 20

Answer 2

Answer:

We can find the value of 1 cone using the given information.

Final Answer: 1 cone $=20$

Step-by-step explanation:

From the given question, First we should find the value of chair and find the value of umbrella using the given data in the question.

                              3 chairs $=30$ -------------(1)

            1 chair + 1 umbrella $= 40$ -------------(2)

1 chair + 1 umbrella +1 cone $= 60$ -------------(3)

• Using the equation(1), we can find the value of chair. That is,    

                               3 chairs $=30$

                                1 chair   $=\frac{30}{3}$

                                1 chair   $=10$

• Now apply the chair value into equation(2).Then we can get the value of umbrella.

              1 chair + 1 umbrella $= 40$

                     $10$ + 1 umbrella $= 40$

                            1 umbrella $= 40-10$

                            1 umbrella $= 30$

• Now apply the value of chair and value of umbrella into equation(3).Then only we can get the value of 1 cone.

1 chair + 1 umbrella +1 cone $= 60$

                   $10$ + $30$ + 1 cone $= 60$

                          $40$ + 1 cone $=60$

                                 1 cone $=60-40$

                                 1 cone $=20$

Final Answer:

1 chair $=10$

1 umbrella $=30$

1 cone $=20$
