The digits of both the two-digit numbers in the first calculation below have been reversed to give the two-digit numbers in the

Semenov [28]

Answer and Step-by-step explanation:

The computation is shown below:

As we assume a and b are together and c and d are together

So, the equation would be

$= ab \times cd$

$= (10a + b) \times (10c + d)$

= 100ac + 10(ad + bc) + bd

Now another equation i s

$= ba \times cd$

$= (10b + a) \times (10d + c)$

= 100bd + 10(ad + bc) + ac

Now take both equations together

So,

100ac + 10(ad + bc) + bd = 100bd + 10(ad + bc) + ac

99ac = 99bd

ac = bd

Now Like here a = 2 b = 10 and c = 5 d = 1

So,

ac = bd = 10

So we can take an example like this

So, by considering the

$62 \times 13 = 806$

And,

$26 \times 31 = 806$

We can the same amount

So in the given question, the choices are not there so we can calculate by the above method

The initial expression is:

$-10+\frac{r}{5}=1$

So we can solve for r so:

$\begin{gathered} \frac{r}{5}=1+10 \\ r=11\cdot5 \\ r=55 \end{gathered}$
