I have been here with a small trick , u can choose any one number between 1 to 10 , multiply it by 2 , then add 20 to it
after that , divide ur result by 2 and subtract the number u have choosed in the starting from the result
I bet the answer is 10

Answer 1

I took 7
7×2=14
14+20=34
34/2=17
17-7=10
U r right

I was knowing this from before. It is really a cool trick.
