In a new problem setup, Sarah's teacher asks her to substitute numbers for \(f\), \(g\), \(h\), \(i\), and \(j\) in the expression \(f-(g-(h \times (i-j)))\) and evaluate the result. Sarah neglected the parentheses but multiplied and subtracted correctly and obtained the correct result by coincidence. The numbers Sarah substituted for \(f\), \(g\), \(h\), and \(i\) were \(2\), \(4\), \(5\), and \(10\), respectively. What number did she substitute for \(j\)?
**A)** 15
**B)** 20
**C)** 25
