To solve this problem, we can use the principle of moments.
The moment of the ruler about the pivot point A is equal to the moment of the body hanging from end B.
Let the mass of the ruler be M grams.
The moment of the ruler about point A is given by:
M * 18 = 35 * 48
Solving for M:
M = (35 * 48) / 18
M = 93.33 grams
Therefore, the mass of the ruler is 93.33 grams.
