Let the number be x.
According to your question,
x + 3x = 100 ( Equation)
thus, 4x = 100
Thus, x = 100/4 = 25
Thus, the number is 25 (Solution)
X + (3 × X) = 100
25 + (3 × 25) = 100
The number is 25, found by solving the equation x + 3 x = 100 which simplifies to 4 x = 100 . Dividing both sides by 4 gives x = 25 .
