An amount of money is to be distributed among Faruk, Vasim and Ranjith in the ratio 3 : 3 : 7. If Vasims share is Rs. 1500, what is the difference between Faruk's and Ranjith's shares?  Pick one:	A) s 1200	B) s 1500	C) s 1600	D) s 2000	E) s 1700

Rationale: "explanation : let p = faruk , q = vasim , r = ranjith let p = 3 x , q = 3 x and r = 7 x . then , 5 x = 1500 ? x = 500 . p = 1500 , q = 1500 and r = 3500 . hence , ( r - p ) = ( 3500 - 1500 ) = 2000 answer : d"
Answer: D
