Hi,

The Problem description is not precise, could you provide clear problem solving strategy.

Thanks.

If 2s > 8 and 3t < 9, which of the following could be the value of s-t?

I. -1

II. 0

III. 1

A. None

B. I only

C. II only

D. III only

E. II and III

we have two equations..

2s > 8 .. s>4, so' s' can be 4.1,5,5.05 etc

and 3t < 9 .. t<3 so 't'can be 2.9999, 2,-1 etc..

if we take the lowest possible difference between s and t, we will take lowest value of s, which is just above 4 and highest value of t, which is just lower to 3..

s-t >4.0000000001 -2.999999999 .... so

s-t>1therefore all values of -1,0,1 are not possible

ans none A

hope it helped
