I believe if x, y, z are consecutive, they should be in order.kstv wrote:Good pointlayzzer wrote:I'm reposting the following
My question then,
now when a questions states numbers x, y, z are consecutive numbers, does it necessarily mean that x is the smallest, y is the middle number and z is the largest?
1) x+z is a multiple of 10
since sum of two consecutive nos cannot be multiple of 10, x and z are not consecutive nos. So x and z are the smallest and the largest nos. in the series or vice versa. But it is not Suff to say whether N is a multiple of 10.
2) y is multiple of 10. but y can be the first , middle or the last number. Only if y is the middle value than N is a multiple of 10. Insufficient.
Combining it is possible to deduce that y is the middle no. Rest is the same.
OK IMHO it is C.
For instance, we cannot say 3, 2, 4 are consecutive numbers as 2 is not consecutive to 4.
unless the numbers are in order 2,3,4 , they r not consecutive.
same applies when x, y, z are consecutive
IMO B
