- If x divisible by 75 then x is divisible by both 25 and 15.
Given A,B,C,D options are multiple of 100=>divisible by 25 and 10 so we just need to check whether every given option is divisible by 3 and 4 or not bcz 75=25*3,40=4-10;
x is divisible by 3 ->sum of digits is a multiple of 3,
x is divisible by 4-> last number formed by last two digits is a multiple of 4;
But it is 40 ->so we consider digits @10's and 100's position.
