Answer:

The two numbers are 30 and 40

Step-by-step explanation:

Let the rational between the two numvers be x

The ratio of two numbers is 3:4.

Thus the two numbers are 3x and 4x

If 5 is subtracted from each of the numbers the ratio becomes 5:7

After substraction of 5, the numbers will be 3x - 5 and 4x - 5. Their ratio

3x - 5 / 4x - 5 = 5 / 7

Solving the equation by cross multiplication

7 (3x - 5) = 5 (4x - 5)

21x - 35 = 20x - 25

21x - 20x = 35 - 25

x = 10

The rational is 10, hence the numbers are

Obe number 3x = 3 × 10 = 30

Second number 4x = 4 × 10 = 40

Thus, the two numbers are 30 and 40
