Question

7,5=101 3,8=28 5,4=? 6,2=24

Answer 1

answer -7,5 =101

6,2 =24

3,8 = 28

To find:

5,4 =?

Solution:

In the given question second equation is wrong if this equation value is 20 then the solution can be defined as follows:

Apply formula:

\begin{gathered}(A, B) = A\times B\times(3+0)-4\\\ Then,\\(C, D) = C\times D\times(3+0-2)+4\\\ then \ the \ series\ would \ be\\(E , F) = E\times F\times (3+1)-4\\\ so \ next \ format \ is\\(G, H) = G\times H\times(3+1-2) +4\end{gathered}

(A,B)=A×B×(3+0)−4

Then,

(C,D)=C×D×(3+0−2)+4

then the series would be

(E,F)=E×F×(3+1)−4

so next format is

(G,H)=G×H×(3+1−2)+4

Solve:

\begin{gathered}(7, 5) = 7\times 5\times (3+0) - 4 = 101\\ (6, 2) = 6 \times2 \times (3+1-2) -4 = 20 \\ (3, 8) = 3 \times 8\times (3+0-2)+4= 28\\(5, 4) = 5 \times 4 \times (3+1) -4 = 76 \\\\\end{gathered}

(7,5)=7×5×(3+0)−4=101

(6,2)=6×2×(3+1−2)−4=20

(3,8)=3×8×(3+0−2)+4=28

(5,4)=5×4×(3+1)−4=76

The final answer is "76".
