Question

54*36=174
27*13=19
43*92=176
24*52=?

Answer 1

Given :

54×36 = 174, 27×13 = 19, 43×92 = 176, 24×52=?

To find :

24 × 52 = ?  on the basis of the given pattern.

Explanation:

Here is given pattern :

x₁ × x₂ = y

The expression will be :

y = -126.034 + 4.891785 (x₁) + 0.996601 (x₂)

Now put the value in place of x₁ and x₂

(1)  -126.034 + 4.891785 (54) + 0.996601 (36) = 174

(2) -126.034 + 4.891785 (27) + 0.996601 (13)  = 19

(3) -126.034 + 4.891785 (43) + 0.996601 (92) = 176  

Therefore,

(4) -126.034 + 4.891785 (24) + 0.996601 (52) = 43

Then 24 × 52 = 43
