Question

If $a\ast b$ denotes the larger of ${}^{\prime }{a}^{\prime }$ and ${}^{\prime }{b}^{\prime }$ and if $aob$ = $(a\ast b)+3$, then write the value of $\left(5\right)o\left(10\right)$, where $\ast$ and $o$ are binary operations.

Answer 1

Given that
$aob$ = $(a\ast b)+3$
$\therefore$ $\left(5\right)o\left(10\right)$ = $(5\ast 10)+3$
= $10+3$
[ $\because a\ast b$ = larger of $a$ and $b$]
= $13$
