The product of the digits of a two-digit number is 24, and reversing the digits increases the number by 18. The number is:
Answer: B
Reversing adds 18, so \( 9(b-a) = 18 \) and \( b - a = 2 \); the digits also multiply to 24.
\[ a(a+2) = 24 \quad\Longrightarrow\quad a = 4, \ b = 6 \]
\[ \text{number} = 46 \]
