"I am a number,
Tell my identity!
Take me twelve times over,
And add a fifty!
To reach a double century,
You still need thirty!"
​Who I am?

Dear Student,
Let the number be x.


Taken 12 times over, the number becomes 12x.When 50 is added, the number becomes 12x+50.To reach double century (200), 30 has to be added to 12x+50.Thus,12x+50+30=20012x+80=20012x=200-8012x=120x=10So, the required number is 10Regards

I agree with ayush. The answer is 10. You need to solve this backwards.

lets take the number as x
12x+50+30=200
try to solve the equation
  • 0
you will get x=10

The number is 10 because if we multiply it with 12 we get 120 and add 50 we get 170 and therefore it is 30 less than double century which means 200.

First add 50 +30 = 80 - 200 = 180 Try to solve the solution

Answer is number 10because 10 + 120 = 130 
130 + 50 = 170
170 + 30 = 200 (200 - 30 = 170)
