Final answer:

To solve the word problem, we convert the verbal statements into an equation, simplify and solve for the variable. The solution to the equation yields the number as 52.

Step-by-step explanation:

The student's question involves forming an equation from a word problem and solving for the unknown variable. The key is to translate the verbal description into a mathematical statement.

Let's break down the question:
"10 less than 5 times the value of a number" translates to 5n - 10.
"10 times the quantity of 12 more than 1/4 of the number" translates to 10*(1/4n + 12).

Now, we can set up the equation:
5n - 10 = 10*(1/4n + 12)
Solving this equation involves distributing the 10 on the right side, moving all terms to one side to set the equation to zero, and then solving for n.

  1. Multiply out the right side: 5n - 10 = 10/4n + 120
  2. Simplify the equation: 5n - 10 = 2.5n + 120
  3. Get all n terms on one side: 5n - 2.5n = 120 + 10
  4. Simplify and solve for n: 2.5n = 130
  5. Divide both sides by 2.5: n = 52

The number in question is 52.
