Guys, here is a very simple DS, just want to confirm the answer..
If n is an integer and 100 n n? (1) N/36 is an odd integer. (2) N/45 is an even integer. Another PS (sorry , i know that there is a different thread), i just want to make sure that my answers, which seem to be not matching to OA, are right.. At a certain company, each employee has a salary grade s that is at least 1 and at most 5. Each employee receives an hourly wage p, in dollars, determined by the formula p = 9.50 + 0.25(s 1). An employee with a salary grade of 5 receives how many more dollars per hour than an employee with a salary grade of 1? A.$0.50 B.$1.00 C.$1.25 D.$1.50 E.$1.75
Cheers
1) Ans B
St 1 :There are 2 odd multiples of 36 between 100 and 200 ..not suff St 2 : Only one even multiple of 45 between 100 and 200 ..suff
2 ) difference is 0.25 [ (5-1) - (1-1)] = $ 1 ...Ans B

HuH...Thats what i got in 2 mins for both of them , was just giving a test and answers, I found were-> for first showed: C, and the second one 1:25$....feeling relieved...Answers almost shocked me as i felt such lolly-pops are giving me jitters..
My answers and explanation in Red. skipping question 1 as i saw your post indicating typo :p. will check it later.
try the following puys:
1) Is x^y 1) aEquation boils down to (a-b)^2 >1 This is possible when absolute value of (a-b) is greater than 1. 1 doesn't give any info. B clearly mentions it hence the ans: B
3) In the fraction x/y, where x and y are +v integers, what is the value of y? 1) the least common denominator of x/y and 1/3 is 6. 2) x=1
x/y is a fraction. y can be 2 or 6. hence a is insuffucient. 2 doesnt give any info. Ans : E
4)If x is a +ve integer and w is a -ve integer, what is the value of xw?
1) x^w= 1/2 2) w=-1
1. x^w = 1/2 is only possible when x is 2 and w is -1. note that both x & w are integers and its given that x>0 and w 2. w=-1 this value insufficnt to get xw
Ans : A
5) Is x/m (m^2+n^2+k^2) = xm+yn+zk? 1) z/k = x/m 2) x/m = y/n Simple substitution using both 1 & 2 will give the value. Ans: C
6)if k and n are integers is n divisible by 7? 1) n-3 =2k 2)2k+4 is divisible by 7.
1. Many combinations of n and k hence insufficnt. 2. doesnt say anything about n hence insufficient.
Using both 1 & 2: n = 2k + 3 = (2k + 4) -1 since 2k + 4 is divisible by 7, n/7 will have remainder -1 hence not divisible. Ans : C
These are all ques from OG quant, the green book. I found them to be tricky so I posted them. I will try to post similar ques for all sections in coming days.
SO the OAs are ( many of the puys got them correct)
