Answer:
The correct answer is 24.
Explanation:
To be able to solve this exercise we must begin by analyzing the information we have:
We know that Pill has 3 times as many rocks as peter, and the total of rocks is 48.
Let the number of rocks Peter has be x, then:
Three times x would be: 3.x
Therefore the equation would be as follows:
3x + x = 48
4x = 48
x = 48: 4
x = 12
If we now know that x represents 12, we must only multiply it by 3 to know how many rocks Pill has:
3 . 12 = 36
Therefore, if Peter is 12, and Pill 36, then Pill has 24 rocks more than Peter.
