Which one of the given numbers is completely divisible by 45?

A. None of these

B. 165642

C. 202860

D. 112330

• To be divisible by 45 number has to be divisible by both 9 and 5.
  If number ends with zero or five then it'll be divisible by 5.
  For 9, add all the digits and if addition of all the digits is divisible by 9 then number'll be divisible by 9.
  So, option (C) 202860 => 2+0+2+8+6+0= 18 which is divisible of 9. Last digit is 0, means divisible by 5.
  So, option (C)202860 is answer.

• 202860 is the answer
  45 can be written as 9*5
  here the numbers divided by 5 is 202860 and 112330 because unit digit is 0
  the number divided by 9 from these two is sum of digits should be divided by 9
  2+0+2+8+6+0=18 (divisible by 9 )
  1+1+2+3+3+0=10(not divisible by 9)
  
  so 202860 is divisible by 45

• 45 factorials are 3,5,9,45
  2+0+2+8+6+0=18 ie divisible by both 3,5,9&45 (c) is correct

• *check the last no first.it should be 5 or 0
  *if above is satisfied,then add all the digits up to get a single digit.if it is 9
  ,it is divisible by 45.
  
  b)165642.
  last no is 2 .It is not.
  c)202860.
  last no is 0.so add all digits 2+0+2+8+6+0=18;
  1+8=9;
  so it is divisible by 45.
  d)112330
  last no is 0.so add all digits 1+1+2+3+3+0=10;
  1+0=1;
  it is not 9.So it is not divisible by 45.

• ans:c
  45=9*5
  last digit 0 divide by 5
  sum is 18 divide by 9
  so c is correct

• ans:A
  
  sol:
  For a number to be divisible by 45 it should be divisible by both 5 and 9.But all the given numbers are not divisible by 9

• Anybodgot mail from amcat the test conducted on 19 aprill pls rply me
  
• 10 years agoHelpfull: Yes(0) No(3)
• 2+0+2+8+6+0=18,we check divisibility of 45,means it is div by 5 and 9 also
  
• 10 years agoHelpfull: Yes(0) No(0)
• c, lasting with 0 so divisible by 5 and try with 9
• 10 years agoHelpfull: Yes(0) No(0)
• c) is divisible by 45 as it is divisible by 5 and 9
• 10 years agoHelpfull: Yes(0) No(0)
• option c is completely divisible by 45 as it is divisible by both 5 and 9
• 9 years agoHelpfull: Yes(0) No(0)
• 202860 divide by 9&5
  also divide by 45
• 9 years agoHelpfull: Yes(0) No(0)
• 9*5=45
  num must be devided by bth d nums
  C be the ans
• 9 years agoHelpfull: Yes(0) No(0)
• c is write
  45=9x5
  so no. should be divisible by both 9 and 5.
  as only c,d option is divide by 5.
  so now check for 9.
  no. having sum divisible by 9 is divisible by so c option is correct.
• 9 years agoHelpfull: Yes(0) No(0)
• 202860 becouse 45=9*5
  then no. should be divided by 9 and 5 both so that ,only no. will be divided by 5 when unit digit 0 or 5
  and for 9 no. will be divisible by 9 if some of all digit no. will be divisible by 9.
  so that 20286 is ans
