1. t is less than 0

T is negative and K is to the left of T so K is negative as well

negative*negative = positive

and any positive will be to the right of t when it's negative

A is sufficient

2. k is less than 1

if T is 10 K could be 1/2 and kt would be to the left of T
if T is -1 K could be -2 and kt would be to the right of T

Insufficient

(1) t is less than 0

(2) k is less than 1



Please explain your answer


I will go with A.

(1) t -ve , so k is -ve then kt = +ve Sufficient
(2) k -ve means t can be = +ve or -ve. Insffucient

A.

(1) T is negative. So is K. Product is positive, i.e. to the right of 0 and T. SUFF
(2) K and T could be positive. If K<1> 1 the product will give a number to the left of T. T may also be less than 1, and if it is negative, the product KT will be positive and greater than T. INSUFF

A

1 k neg, therefore t neg, and product will always be positive therefore to the right of t

2 k less than 1, so k can be positive or negative. depending on sign of t, kt will either be positive or negative. no way to tell. insufficient

I go with C. I think not only integers can be on the number line.

It doesn't matter whether the numbers are integers or not. We just need to know if the new number is greater than t. If T is negative and k is negative, the product must be positive

A it is
St 1: if T<0 , and K is left of t , this means K is also a negative numbers smaller than T
assume T = -2 and K =-3... product of 2 negative will be +ve , hence to the right of T....sufficient

St2 : K <1 ,assume K = -1 and t = 1/2 product is -1/2 .. this is to the left of t
assume k = k = -2 and t = -1 product = +2 , this is to the right of t.. ............thus insufficient

Here's your case.

For 2, T can be less than 0 or T can be greater than 0. Thus product kt's position depends where K and T are.

OA A.

I also drew the number line and agree with you. Just to make the second case a bit more clear:

We know that k<1.
What we don't know is if t is also LT 1.
Also, LT1 could mean 0.5 or it could be a negative number.

For 1, we know that k< t<0, so they are both negative. This would make their product positive and greater that t.

Is kt>t?

Statement 1:
If t < 0. Then the number to the left would also be negative. Product of two negatives would be greater (and to the right) of the two integers. Sufficient

Statement 2:
Multiple cases possible. Insuff.

Option A

(1) t < 0

(2) k < 1


Question: Is the product kt to the right of t
3 combinations are possible:
1. K.....T......0 --> YES
2. K.....0.....T --> No
3. 0.....K.....T --> YES (if k > 1)

(1) t < 0 --> see above, straight yes, sufficient
(2) k < 1 --> could be combi 2 or 3. Not sufficient

I took 'left' as T K and not K T.

Can we expect questions with such ambiguity on the GMAT?

The number k is to the left of the number t means ______K_______T__________. There is no ambiguity there.

Draw number line, place k and t as mentioned in question.
A --> ____k____t______0__
as k and t both are left of zero, (negative) their product will be positive.

B --> multiple possibilities.
as on below number lines (i am drawing only 3, u can try more by moving t around 0 and 1)
____k__0__t________ kt negative so on left of t
____k__ t___0_____ kt positive so on right of t
_0__k___1___t________ kt is positive but k<1 so kt<t therefore kt on left of t
So the answer A.
Hope this helps!

"Number k" means k can be integer, fraction, decimal anything? Bunuel

Yes, k can be any real number.
