Its E.

Taking A and B together.

Let T be the total number of boxes packed.

L+R+P = T
L = 0.3T
R = P + 10

L+R+P = 0.3T + P+P+10 = T
P= (0.7T-10)/2

therefore R/P = (P+10)/P = (0.7T+10)/(0.7T-10)

which is not possible to know unless we know T.

Must be E

Total = x
Linda = L
Robert = R
Pat = P

Find R/P

St1: L = 0.3x : INSUFF
St2: R = P + 10, R/P = 1 + 10/P: INSUFF

Combined : Clearly INSUFF

Guys answer is C since we are looking at RATIO not at number of books.
Let say we have 100 books.
L - 30
R - x+10
P - x
30+x+10+x=100 => x=30
R/P=40/30=4/3

What if we have 200 boxes

linda packed 60 boxes

between 140 boxes, Robert packed 75 and Pat packed 65 (total=140)
ratio = 75/65 = 15/13 which is not equal to 4/3

So, we need to know the total # of books in order to find the ratio as it will vary. I think if (2) had said "B) Robert packed 10% more boxes of books than Pat did" then we could have gone your route.

Linda, Robert and Pat packed a certain number of boxes with books. What is the ration of the number of books that Robert packed to the number of books that PAt packed?

1 Linda packed 30% of all the boxes
2 Robert packed 10 boxes more than Pat.

A good question to share.

Please can somebody tell me the rank of this question I find it pretty easy and my collegue told me it is a 600+ question

Answer is E. Since the relationship between the boxes and the books is not established in the question.

Not sure of the rank of this question. Maybe a sub-600 category question.

Should be E.

1) Not sure if there are boxes which are not packed.
2) No definition of ratio can be derived.

I would say it is some where between 500- 600. I could be wrong though..

1 is obviously not sufficient since it speaks about linda
2 .says R = P+10
not sufficient cant get R/p
combine them
since linda packed 30 percent therefore r and P packed
70 percent ..let total no be x
R + P = .7x
from statement 2
p+10 + P = .7x
cant still find P and hence cant find r
E
