• How can it be 32 , as the question is "number less than 64" and all of you include 64 in multiples of 4
• 8 years agoHelpfull: Yes(2) No(1)
• the answer would be 26 as i addition to the no's given by Yashika two more will add up
  1. 48 as it is divisible by 8
  2. 0 as 0 is divided by 0 and it will count as we are taking about whole no's
• 8 years agoHelpfull: Yes(1) No(0)
• it will be 23

• 11=10+1,12=10+2,15=10+5,here when the unit digit number divides 10 without any remainder then that no is divisible by its unit digit number..similarly21=20+1,22=20+2,24=20+4,25=20+5,here unit digit number must divide 20 similarly counting the ans is 23
