Answer:
The first number and second number are 10 and 20 respectively.
Step-by-step explanation:
Let the numbers be x and 2x
By condition,
x + 10 / 2x + 10 = 2 / 3
=> 3(x+10) = 2(2x+10)
=> 3x + 30 = 4x + 20
=> 3x - 4x = 20 - 30
=> - x = - 10 => x = 10
First number = x = 10
Second number = 2x = 2×10 = 20
