The greatest number of four digits which is divisble by 15, 25, 40 & 75 is:

A.9000
B.9400
C.9600
D.9800

• LCM of 15,25,40,75 is 600
  600 is the multiple of 9000,9600

• 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.
  Now u can solve each!!
