Prime factors were just a way to get to the lowest levels of factors..u r right that alone getting into terms of prime integers doesnt suffice.. But if you see 8! , you only 2 is having power >=6 .. any combination of factor which you can thus derive is not even close to 6 in its power.. Either you...

IMO B.

What is the value of A.

a^n is multiple of 8!.

the 1st statment says that a^n = 64.it could be 2^6 or 4^3.

Insufficient.

the 2nd statment says that n = 6 i.e a^6 is multiple of 8!.

sufficient.

Its a C trap question so be careful.

IMO C. Basically the question is asking for what is the value of X? From 1st We get two equation X = q x 2 + 1 (q = quotient) the other equation is X = q x 3 + 0. so it could be 9 or 21. Insuffcient. From 2nd statment we get X = q x 12 + 3. it could be any number 15,27,39 etc. Insufficient. By takin...

IMO E. Question is bassically asking that what is the value of z and n. From 2nd we get that, Z>0 so it could be a fraction or could be digit. so satisfy this statement n has to be 0 to make this equal to 1. i.e 1/2^0=1. Insufficient. From 1st we get that N is not equal to 0. completely opposite of ...

IMO B.

5 nos are 0 2 4 6 8.

So we can see that every value is 2 units apart.

And the median is 4.

And if we will add 4 and 4.the SD will not change.

0 2 4 4 4 6 8. In this median remain the same(4).

and equal value on both the sides to the median.

So that means the maximum value will be less then $800,000.Sufficient From 2nd we get, SD is $200,000.that means every ...
