Question

In a certain code language if $44\times 44=4444$ and $34\times 52=5423$ then find the value of $81\times 46$ in the same code language.

• A. $1648$
• B. $8461$
• C. $8164$
• D. $4168$

Answer 1

The correct option is D $4168$

In a certain code $44\times 44=4444$ and $34\times 52=5423$.

The second digit doesn't change its place whereas $1^{st},3^{rd}$ and $4^{th}$ digit shifts by one place.

$\therefore$ $81\times 46=4168$.

Hence, option D is correct.
