An engineer wife called her scientist husband saying
that she has forgotten the ATM password. The
scientist replied, "Add your year of birth to the
smallest 4-digit perfect square number". If the
engineer was born in 1988, then "****" stands for?

Dear Student,

The smallest four digit number is 1000,which is not a perfect square as 1000 ≈ 31.622 Hence the number after 31.622,that is ,32's square will be a four-digit perfect square  32×32=1024 Hence,1024 is the smallest four-digit number which is a perfect square.The smallest 4-digit perfect square is 1024.Year of birth of engineer = 1988So, ATM password = 1988+1024 = 3012 Ans
