Question

22+4=48,13+0=0,80+2=28,67+9=?​

Answer 1

Given :

22+4 = 48, 13+0 = 0, 80+2 = 28, Then, 67+9 = ?

To find :

67+9=?  on the basis of the given pattern of addition.

Explanation:

Here is given pattern :

x₁ + x₂ = y

The expression will be :

y = -0.832 + 0.064 (x₁) + 11.856 (x₂)

Now put the value in place of x₁ and x₂

(1)  -0.832 + 0.064 (22) + 11.856 (4) = 48

(2)  -0.832 + 0.064 (13) + 11.856 (0) = 0

(3)  -0.832 + 0.064 (80) + 11.856 (2) = 28

Therefore,

(4)  -0.832 + 0.064 (67) + 11.856 (9) = 110

Then 67 + 9 = 110
