Can someone please explain to me why the answer to this DS problem is D although i think is E
If tower A is less than 100 feet tall, is tower B taller than tower A?
(1)Tower B is 3 times as tall as tower A.
(2)Tower A is 30 feet shorter than tower B.
Because
Steam of the question implies that the height of tower A is anything between 1 and 99 therefore
ST1 Tower B can be 3(10) = 30 as well as 3(50) = 150 hence INSUFFICIENT
ST2 Tower A = Tower B - 30 we still do not know the height of Tower A
INSUFFIENT
both statements taken together will still be insuffient because ST1 has more than one value.
Thus i think the correct answer should be E
I would like to know if anyone has anything contrary or point out my mistake to me please
