Let the parts are x and (x + 10)

According to the question,

 \frac{x + 10}{x} = \frac{5}{3} \\ \\ \\ 3(x + 10) = 5x \\ \\ 3x + 30 = 5x \\ \\ 30 = 5x - 3x \\ \\ 30 = 2x \\ \\ \frac{30}{2} = x \\ \\ 15 = x

Parts are x = 15 and (x + 10) = 15 + 10= 25



Number is 15 + 25 = 40
I hope this will help you

HumanZombie: Why is that 5x?
abhi569: Wait
HumanZombie: x is one of the numbers
abhi569: by cross multiplication
abhi569: x is multiplied by 5
abhi569: Then 5x comes
HumanZombie: and 5 and 3 are in ratio two 2 unknown numbers so they should have a variable multiplied to them
