Question

I think of a number. I add 1090 to the number.

I subtract 450 from the result. The answer is 760.
What is the number I first thought of?

Answer 1

120 is the number u thought of first

Explanation:

1090-450=640

if we add 120 into 1090

then it will be 1210

so 1210-450=760

Answer 2

120

Explanation:

call the number x,

then x+1090-450

so x+640=760

x=760-640

x=120

hope this works :)
