kondor19780726 [428]

Answer:

Yes, you are correct.

Step-by-step explanation:

$\text{Let the number of puzzle solved by Child B is} x\text{.}$

$\text{Then the average number of puzzle solved is}$

$\frac{5x+x+(x+4)}{3}=13$

$\frac{7x+4}{3}=13$

$7x+4=39$

$7x=35$

$x=5$

$\text{Therefore, the number of puzzles solved by child A is }5x=5\cdot5=25$

$\color{blue}\text{A little tips here: You can check it by substituting your answer to the original equation.}$
