Question

________ 3 digit number does not look the same after a half turn.
(a) 808 (b) 181 (c)881 (d) 101​

Answer 1

b) 181

because after half turn(( second digit change position with first digit), just guessing) the digit will be 811 which is not same hence b is the answer

also if we half turn 808 and 101 then it will form 088 and 011 a two digit number which is not required

for 881 after half turn the result will be same 881 which is not asked in the question

I guess the answer is right or maybe not
