Four friends, P, Q, R and S have $1400 with them. Does P have the highest amount among the four friends?

(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

what if the amount of money each has is a decimal? Nowhere in the question mentions that the amount of money is an integer?
