if n is an even integer,which of the following is an odd integer?
A)3n-2
B)3(n+1)
C)n-2
D)n/3
E)n^2
Read Solution (Total 18)
-
- Option (b)3(n+1) is answer
Assume n=6(even integer)
so 3(6+1)=>21(Odd integer)
Not only 6, take any even integer it satisfy the option (b) condition - 12 years agoHelpfull: Yes(11) No(4)
- its B)3(n+1) coz take any even no like 2 put in the solution set u'll get the answer
- 12 years agoHelpfull: Yes(3) No(0)
- if we take n=2 then,a/c to the option B ->3(n+1)i.e3*3=9,which is an odd integer
- 12 years agoHelpfull: Yes(2) No(0)
- Ans: B because if any even integer added with 1 then it become odd integer and if it is multiplied by 3 then answer becomes odd integer
- 12 years agoHelpfull: Yes(2) No(0)
- Answer B) 3(n+1).
Because n+1 is odd integer and multiplying an odd integer by 3 will give an odd integer. - 12 years agoHelpfull: Yes(1) No(0)
- b......let n=6 den n+1=7.....so3(n+1)=21
- 12 years agoHelpfull: Yes(1) No(0)
- odd*odd=odd always...
- 12 years agoHelpfull: Yes(1) No(0)
- ans-B 3(n+1),
- 12 years agoHelpfull: Yes(1) No(0)
- Ans. option B) 3(n+1)
If n is even integer then n+1 will always be an odd integer. When odd number is multiplied by an odd number it will be odd. So 3(n+1) is an odd integer. - 12 years agoHelpfull: Yes(0) No(0)
- If n is even integer. then 3(n+1)is odd integer.
- 12 years agoHelpfull: Yes(0) No(0)
- ans=B,3(n+1)is always a odd integer if n is even bt oders r either even or float no..
- 12 years agoHelpfull: Yes(0) No(0)
- Answer B is right answer
3(n+1)
if n = 2
3(2+1)
3(3)
9 - 12 years agoHelpfull: Yes(0) No(0)
- 3(n+1)
using induction method .. - 12 years agoHelpfull: Yes(0) No(0)
- if n is even n+1 is odd and 3(n+1) also odd
answer B - 12 years agoHelpfull: Yes(0) No(0)
- assume n=2 and then substitute in all cases...nw 2ng condition will be a rite one bcz.3(2+1)=9 which is odd
- 12 years agoHelpfull: Yes(0) No(0)
- The answer is B
3(n+1) - 12 years agoHelpfull: Yes(0) No(0)
- 3(n+1) since 3 is odd and n+1 is odd as n is even..now odd*odd always gives odd therefore 3(n+1) is odd
- 12 years agoHelpfull: Yes(0) No(0)
- option b is correct assume n=2
- 11 years agoHelpfull: Yes(0) No(0)
