I think the answer is aaaaaaa

the question is asking is 2(L+B) > LB or is 2L+2B > LB

from option a if width =B=2 than 2L + 2 * 2 > 2l
thus solving this we get 2>0. Hence perimeter is greater than area

from B nothing help

X= 3^N AND Y= 3^M . IS X >2Y ?? 3^n > 2*3^m ?? A) n=m+1. thus lhs = 3*3^m. as 3>2 sufficient B) n=2M. 3^(2m) > 2* 3^m ?? or 3^m * 3^m > 2*3^m or 3^m>2??? if m=0, 1>2 false if m=1, 3>2 true Insufficient IMO A THANKS FOR YOUR POST. BUT WE DON'T KNOW THAT BOTH M AND N ARE POSITIVE OR NEGATIVE INTEGER....

DS INTEGER

Q: IF M AND N ARE INTEGERS, AND X= 3^N AND Y= 3^M .IS X >2Y ?

A: N= M+1
B: N= 2M

DS: FACTORS

Q: P IS A FACTOR OF Q^2 . NEITHER P NOR Q IS A PRIME NO.
IS Q/2 A FACTOR OF P^2 ?

1: P/ 4 IS AN INTEGER, WHILE 4 IS NOT A FACTOR OF Q
2: P = 2^K , WHERE K IS A POSITIVE INTEGER


OA. IS C BUT MY ANS. IS EE
HELP

DS: MEAN

Q Nine positive integers are contained in Set N. The median of Set N is the integer x, and all the values in Set N are 3x or smaller. What is the largest possible average (arithmetic mean) of set N?

A: X B: 17X/9 C: 17X/9 - 1 D: 17X-4 /9 E: 3X

MY ANS B IS WRONG

DS INTEGER

For all values of the integer x, is the product (x + 3)(x2 + 3x + 2) divisible by 4?

1) is an odd integer
2) x is divisible by 16


MY ANS D IS WRONG[spoiler][/spoiler]

QUANT DS

Q: IS A^2 + B^2 > 100 ?

A: (A + B)^2 > 200
B: 2AB <100



MY ANSWER IS C. BUT OA IS A

ans is ddd from 1: |x + 3| = 4x - 3 if x > 0, than x+3 = 4x -3 by solving this we get 6= 3x. thus x =2 if x< 0, than x +3 = -4x + 3, by solving this we get x =0 . but if we put x=0 in the question than we see that |x + 3| is not equal to 4x - 3. thus x is not equal to 0 (YOU CAN SEE THAT IF WE PUT X...
