Answer
The three symbols represent $1$, $5$ and $0$ respectively.
Work Step by Step
Since there are four dots in the starting of Mayan symbols in the Exercise 131 and the first number which is multiplied with $20$ raised to some power is $4$.
Each dot represents $1$.
The next symbol in the Mayan symbols is two dots and three lines.
And the next number is $17$.
Since two dots represent $2$. That means three lines represent $15$.
That means one line represents $\dfrac{15}{3}=5$.
Since the last number is $0$. That means the last symbol of the Mayan symbols represents $0$.
So, the three symbols represent $1$, $5$ and $0$ respectively.
