"it" is ok fine here because it is also in the first sentence and makes them therefore parallel.

smallest common multiple of two numbers is the smallest number that divides both of them. thus 251 & 251 has smallest common multiple 251

must go with D, if D is not assumed, the investigators job is just to find someone to blame (which they did)

I vote for C & D too

you need to consider only positive integers to get range from here answer is b

line l, y=ax+b in 1) y intercept: x=0 & y=b, a=3b, don't know a, thus cannot answer the question, insufficient in 2) x-intercept: y=0 & x=-b/a=-1/3 b=1 answer b

can I & III be same?

I agree with saurabhinindia

I think the answer is B in statement one we can find number that is an integer when multiplied by 16: 0.125 (which doesn't have the tenths digit zero) but if we take 0.0625 (does) so 1 is insufficient in statement 2: smallest possible nubmer that gives an integer when multiplied by 8 is 0.125, which has the tenths digit nonzero thus sufficient answer is B

it would say that she purchased childrens tickets only. since we don't know from the current formulation of the problem whether she also bought some adult tickets, we cannot answer the question and the statement is not sufficient

its pretty simple actually in statement 1: we know that 10d has the tenth digit 7, thus d must look something like this: 0.07 (or some other numbers instead of 0) and the hundredths Digit is 7 - sufficient in statement 2: similar case, the hundredths Digit is 7 answer d

nenuphani, both solutions are lenght, but only the solutions with all 2 is greatest possible

there is nothing said in the question that would confirm the numbers are different, thus I think the answer is 251

agree with E all the rest have some problems

congrats! its coooooooooooool! good luck!
