I think it should be E. Because 1 does not mention the relationship with P.
2 also does same. When we combine, it still insufficient so it should be E

Statement 1 says Q has five times the money compared to R.
Not sufficient.

Statement 2 says R has 210 greater than that of S.
Insufficient.

Both together:

P+Q+R+S=1400
P+Q+(S+210)+S=1400, because r has 210 greater than s.
P+5(S+210)+S+210+s=1400.
7S+P=140.

Which ultimately says that P doesn't have the highest amount.

Sufficient. Answer is C.

(1) The amount with R is one-fifth the amount with Q.
(2) R has $210 greater than what S has.


We know P+Q+R+S = 1400

(1) 5R = Q
Not Sufficient (R,Q) could be (10,50) or (200,1000)

(2) R=210+S
Not Sufficient (R,S) could be (210,0) or (790,580)

on combining

if S = 0 then R =210 then Q = 1050 then P = 1400-0-210-1050 = Not the highest
if S= 20 then R = 230 then Q = 1150 then P =1400-20-230-1150 = 0 Not the Highest
if S= 100 then R= 310 then Q = 1550 Not Possible
Since S ranges between 0-20 in all cases P is not the highest ...Sufficient
C
