Let the number = x and y
x + y = 4 × (x – y)
x + y = 4x – 4y
5y = 3x
x : y = 5 : 3
Hence, Option C is correct.

Understanding the Problem:
The problem states that the sum of two numbers is equal to four times their difference. Let's denote the two numbers as x and y.
Formulating the Equation:
According to the problem, we can write the equation as:
x + y = 4(x - y)
Solving the Equation:
Expanding the equation:
x + y = 4x - 4y
Rearranging the terms:
y + 4y = 4x - x
5y = 3x
y = 3x/5
Calculating the Ratio:
The ratio of the bigger number (y) to the smaller number (x) is:
y : x
= 3x/5 : x
= 3 : 5
Therefore, the ratio of the bigger number to the smaller number is 3 : 5. Hence, the correct answer is option 'C' (5 : 3).
