please update.
Thank you dp kushwaha,
We have updated the answer.
Question no. 18 and Question no. 24 are same question but your answer is different.
I Think answer is 218 please correct it.
question no. 15, option a and option b are same and not match with gate overflow solution
Dear dpkushwaha,
option a and b are not same.
