Question

If $8\ast 7=56$, $9\ast 6=54$ and $8\ast 3=24$, then find the value of $8\ast 5$.

• A. $55$
• B. $40$
• C. $50$
• D. $44$

Answer 1

The correct option is B $40$

$8\ast 7=8\times 7=56$,

$9\ast 6=9\times 6=54$ and

$8\ast 3=8\times 3=24$
Similarly, $8\ast 5=8\times 5=40$

Hence, B is correct.
