Question

Barry's $6$-digit passcode for internet banking consists of six different digits. If a multiplication sign is placed between the second and third digits and an equal sign is placed between the third and fourth digits, a correct calculation appears. the first digit of the passcode is $6$, the third digit is $5$ and the fifth digit is $2$. What is Barrys passcode?

Answer 1

Finding Barry's passcode:

The given data,

First digit of the passcode is $=6$,

The third digit is $=5$

Fifth digit is $=2$

So consider the six digit passcode be $=6X5Y2Z$

If a multiplication sign is placed between the second and third digits and an equal sign is placed between the third and fourth digits

$\therefore 6X\times 5=Y2Z$

Now if we take $X=4,Y=3\&Z=0$

$$\begin{gathered} \Rightarrow 64\times 5=320 \\ \Rightarrow 320=320 \end{gathered}$$

Which makes calculation correct.

Thus, the passcode is $645320$.
