Question no. 14 your answer not match with gate overflow solution.
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
option a and b are not same.
