- Answer Will Be -->b)32
Divisible by unit digit 2 -->12,22,32,42,52,62(6)
" 3 -->33,63(2)
" 4-->24,44,64(3)
" 5-->15,25,35,45,55(5)
" 6 -->36(1)
" 7-->**
" 8-->48(1)
" 9-->**
" 1-->11,21,31,41,51,61(6)
also 2,3,4,5,6,7,8,9(8)
So total 32 (Answer) - 9 years agoHelpfull: Yes(12) No(5)
- ans is 23
as they have mentioned units place we have to consider only 2 digit numbers
they are

- How can it be 32 , as the question is "number less than 64" and all of you include 64 in multiples of 4
- 9 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 - 9 years agoHelpfull: Yes(1) No(0)
- it will be 23
- 9 years agoHelpfull: Yes(0) No(0)
- how its 32 or 23?
- 9 years agoHelpfull: Yes(0) No(0)
- 23 is the ans
- 9 years agoHelpfull: Yes(0) No(1)
- anwer is b.32
if we include 1to9 we get 32
01,02,03,04,05,06,07,08,09,11,12,15,21,22,24,25,31,32,33,35,36,41,42,44,45,48,51,52,55,61,62,63.

- 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
