To solve the problem step by step, let's denote the three digits of the number as \( a \), \( b \), and \( c \). Since the digits are in geometric progression (GP), we can express them as follows: 1. Let the first digit \( a \) be \( A \). 2. The second digit \( b \) can be expressed as \( A - R \). 3. The third digit \( c \) can be expressed as \( A - R^2 \). Now, we can write the number as: \[ ...
