Question

I am a number,
Tell my identity!
Take me seven times over
And add a fifty!
To reach a triple century
You still need forty!​

Answer 1

Let the no. be x,

ATQ,

7x + 50 +40 = 300

=> 7x = 300-50-40

=> 7x = 250-40

=> 7x = 210

=> x = 210/7

=> x = 30

Answer: 30

Step-by-step explanation:

Let the number be x

therefore depending upon the condition

the equation would be

7x + 50 + 40 = 300

7x + 90 = 300

7x = 300 - 90

7x = 210

x = 210/7

x = 30

The number is 30
