Answer:

80

Step-by-step explanation:

5×4=20

7×4=28

8×4=32

9×4=36

20×4=80

every number is multiplied by 4.

Answer 2

If 5 = 20 , 7 = 28 , 8 = 32 , 9 = 36 then 20 = 80

Given :

5 = 20 , 7 = 28 , 8 = 32 , 9 = 36

To find :

20 = ?

Solution :

Step 1 of 2 :

Find the pattern

5 = 20

The second number (20) is obtained on multiplication of first number (5) and 4

7 = 28

The second number (28) is obtained on multiplication of first number (7) and 4

8 = 32

The second number (32) is obtained on multiplication of first number (8) and 4

9 = 36

The second number (36) is obtained on multiplication of first number (9) and 4

So the pattern is

The second number is obtained on multiplication of first number and 4

Step 2 of 2 :

Find the result

We have to find 20 = ?

First number = 20

So the second number is obtained on multiplication of first number (20) and 4

So the required number

= Second number

= 20 × 4

= 80

∴ 20 = 80

If 5 = 20 , 7 = 28 , 8 = 32 , 9 = 36 then 20 = 80
