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

(1) Linda packed 30 percent of the total number of boxes of books.

(2) Robert packed 10 more boxes of books than Pat did.

St1:- Let total #of boxes=X=L+R+P
L=0.3X
No info on R & P.
So insufficient to determine R/P.

St2:-R=P+10,
No info on X .
So insufficient to determine R/P.

(1)+(2), no additional info on relation between R and X or R and L.
So insufficient to determine R/P.

I) $$\frac{3(P+R+L)}{10}=L$$

II) $$R=P+10$$

II) in I): $$\frac{3(2P+10+L)}{10} =L\implies 6P+30=7L$$

II) in I) $$\frac{3(R+R-10+L)}{10}=L \implies 6R-30=7L$$

We cannot use $$L$$ to compare $$R$$ and $$P$$. E
