hi

let the number be xy'

tens place = 10x

ones place = y

The digit at tens place of a two digit number is 3 more than the digit in units place

x = 3 + y

If unit digit is 2

since the tens place =  3 + y and y = 2

tens place /x= 3 +2

=5

the number is xy

x=5 and y =2

so 52

option a is correct
