Question

given that 20-4=10 and also 30-6=10 then solve 40-8=?

Answer 1

The answer can be 0
20-4=10
20=14
(Replace the value of 20 by 14) 
14-4=10

30-6=10
30=16
16-6=10

40-8=x
40=8
8-8=0

Therfore, the answer can be zero(0)
I am not sure about the answer

Answer 2

Answer:

The value of 40-8 = 10.

Step-by-step explanation:

Number pattern:

• Number pattern is a pattern which a list of number follows a sequence.

        Example:  1, 3, 5, 7, 9

• Here the pattern follows a sequence, where a positive number 2 is added continuously to get the next number.

      Given 20-4 = 10

                 30-6 = 10

     We can write

            20-4 = (20/4)x(2)

                     = 5x2

                     = 10

            30-6 = (30/6)x(2)

                     = 5x2

                     = 10

• In the above set of numbers it follows a pattern where first number is divided by second number and then multiply by 2.

      So, the next value also follows the same pattern.

      Similarly,

             40-8 = (40/8)x(2)

                      = 5x2

                      = 10

             Hence, 40-8 = 10
