The problem:
The product of two successive integral multiples of 5 is 1050. We need to find these two numbers.
Approach:
Let's assume the two numbers as (5x) and (5x + 5), where x is an integer. We can form an equation based on the given information and solve for x.
Solution:
Let's form the equation based on the given information:
(5x) * (5x + 5) = 1050
Expanding the equation:
25x^2 + 25x = 1050
Simplifying the equation:
25x^2 + 25x - 1050 = 0
Factoring the equation:
25(x^2 + x - 42) = 0
Further simplification:
(x^2 + x - 42) = 0
Factoring the quadratic equation:
(x + 7)(x - 6) = 0
Solving for x:
x + 7 = 0 or x - 6 = 0
If x + 7 = 0, then x = -7
If x - 6 = 0, then x = 6
Since we are looking for positive integers, we can discard the negative value of x.
Calculating the numbers:
Using the value of x, we can find the two numbers:
First number = 5x = 5 * 6 = 30
Second number = 5x + 5 = 5 * 6 + 5 = 35
Thus, the two successive integral multiples of 5 that have a product of 1050 are 30 and 35.
Final Answer:
The correct answer is option D, which states that the numbers are 30 and 35.
