Question

4,7=53 ;6,9=87; 1,7=?​

Answer 1

4,7=53 ;6,9=87; 1,7=?

The pattern in the series is :

4 ; 7 = 53

6 ; 9 = 87

1 ; 7 = ?

The logic in the question is

${b}^{2} + a$

$53 = {7}^{2} + 4 \\ \\ 87 = {9}^{2} + 6$

In the same way the answer is :

${7}^{2} + 1 = 50$

Therefore, the answer is 50

Answer 2

$\textbf {Answer =50:}$

$\textbf {let's explain how 50 is come as answer:}$-

$\textbf {\underline {\underline {Case one:}}}$-4,7=53,

Here we first multiplied 7×7=49 then we added 4 on 49 and this became =53,

$\textbf {\underline{\underline {Case Two:}}}$- 6,9=87

Same method we'll apply here,

• 6,9=87
• 9×9=81
• 81+6=87,

$\textbf {\underline {\underline {Case Three :}}}$-1,7=?

• 7×7=49
• 49+1=50

$\textbf {\underline {Therefore 50 come as Answer:}}$
