hey puys can anybody give the answer for this data sufficiency question
A)1 alone is sufficient to answer the questions B)2 alone is sufficient to answer the questions C) both 1 and 2 together are required to answer the question but neither of the two is sufficient to answer the question D)either 1 or 2 alone is sufficient to answer the questions E)neither 1 nor 2 is necessary to answer the question
given below is an equation where the letters represent digits
the digits are unique : possible values of XXX are 111/222/..../999 = 111 * (1/2/3/...9) = 37*3*(1/2/..../9) = 37*(3/6....12/15/18/21/24/27) But as given each of PQ and RQ end with Q and there is only one number which ends with 7 in our possible choices (that number is 27) so again Q = 7 and P+R = 5 P+Q+R+X = 5+7+9

given below is an equation where the letters represent digits
PQ * RQ = XXX. find the sum of P+Q+R+X
1) X=9 2) the digits are unique
using 1) X=9 999=37*27... so it is alone sufficient using 2) XXX can have a min value of 111 and max of 999... so it will always be a of the form 111n i.e. 37*3*n... so either PQ will be 37 or 74 as the digits are unique only 37*27 is a valid combination..so this statement also is sufficient. SO answer might be D
(I) x - y > 1 Means (x+y)(x-y)>0 But it can happen that both (x+y) and (x-y) are less than zero, And still two negative terms multipled will be greater than zero. So (x+y) can be 0 In this case (x+y)>zero. Hence Statement I, insufficient to explain.
(II) x/y+1>0 (x+y)/y>0 for x>y>0 its true. in this case x+y>0 But its also true for 0>x>y, and in this case x+y Hence Statement II, insufficient to explain. Combining I and II together,also leads to two different scenarios, x+y > 0 and x+y
can the Positive integer P be expressed as the product of 2 integers , Each of which is greater than 1??? 1>31
2> P is ODD
1.31
In this case, P can be equal to = 32,33,34,35,36 None of them is a prime number, so yes Positive integer P be expressed as the product of 2 integers, Each of which is greater than 1.
Statement I sufficient. 2. P is Odd Well except 2, all prime numbers are odd, so P can be something like 5,7,17. In that case P cannot be expressed as the product of 2 integers
Statement II, insufficient.
Combining 2 statement P can be equal to =33,35 In both case can be expressed as the product of 2 integers. So Together also sufficient.
The sequence a1, a2,a3..aN..Of n integers is such that aK=K if K is Odd and aK=-Ak-1 if Ken, Is the sum of terms in the sequence positive? A> N is ODD B> an is positive
The sequence a1, a2,a3..aN..Of n integers is such that aK=K if K is Odd and aK=-Ak-1 if Ken, Is the sum of terms in the sequence positive? A> N is ODD B> an is positive
The sequence a1, a2,a3..aN..Of n integers is such that aK=K if K is Odd and aK=-Ak-1 if Ken, Is the sum of terms in the sequence positive? A> N is ODD B> an is positive
Option B is a restatement of Option A. An can be positive only if N is odd. Since A isn't sufficient and B isn't sufficient hence E.
Yesterday Nan parked her car at a certain parking garage that charges more for the first hour than for each additional hour. If Nans total parking charge at the garage yesterday was $3.75, for how many hours of parking was she charged?
(1) Parking charges at the garage are $0.75 for the first hour and $0.50 for each additional hour or fraction of an hour. (2) If the charge for the first hour had been $1.00, Nans total parking charge would have been $4.00.
