Is w a whole number?

3w is an odd number.
2w is an even number.

• neither of the statements justify it. eg: let w=-1; 3*-1=-3 is odd;2*-1=-2 is even; but -1 is not a whole number.So, neither of statements justify it.

• statement 2 is enough to solove this
  
  3w is odd means w may be odd or fraction like 5/3 we can not guess what w is
  
  2w is even so must and should w either odd r even i.e which is whole number . no fraction will give even output

• It may or may not be ODD number
  Let whole number be 2
  3*2=6 which is even
  2*2=4 this is again even.

• no, w is not a whole no. Because, always 2*whole no=even no.
  but 3*whole=odd..it may be or may not be odd no.

• w is not a whole no .
  whole no= 0,1,2,3,4.......
  when we put thise no in the below, condition is not satisfied so w cannot be a whole no.

• 3w is uncertain not always an odd number
  2w is true since its always even
• 10 years agoHelpfull: Yes(1) No(1)
• yes
  3*3= 9
  2*3= 6
  3 is a whole number and w can not be 0 so yes w can be a whole number

• what about the negative numbers then??
• 10 years agoHelpfull: Yes(1) No(1)
• cannot be determined
• 10 years agoHelpfull: Yes(1) No(1)
• 2w is an even because w it is multiplied by 2.
  3w will be odd only when w will be odd

• ya w is whole no.
• 10 years agoHelpfull: Yes(0) No(2)
• w is whole number
• 10 years agoHelpfull: Yes(0) No(1)
• statement 2 alone sufficient and correct to answer
• 10 years agoHelpfull: Yes(0) No(0)
• statement 2 is sufficient
• 10 years agoHelpfull: Yes(0) No(0)
• w is not a whole number, if so w can take the value 0, if w=0 then both statements will fail hence w is a naturla number

• Here they are asking about whole number. (i.e) Whole_number=0,1,2,3,4.....
  So we need to substitute all the numbers in the place of 'w' and need to satisfies the queries.
  Here if we substitute w=1, Then 3*1=3(odd) / 2*1=2(even) satisfies but If we substitute w=2, Then 3*2=6(even) / 2*2=4(even) not satisfied. So w is not a whole number.

• yes.w=1, then 3*1=3 odd and 2*1=2 even

• For one wall 6 6/13 is the answer but they asked to find the days for painting two such walls.so,ans is 12 12/13

• Yes it is a whole number and 2w is an even number.
• 5 years agoHelpfull: Yes(0) No(0)
• yes w is a whole number and 2w is a even number.
