Rs.1210 were divided among 3 person P, Q, R so that P:Q=5:4 and Q: R=9:10. Then R gets the amount?  Pick
A) Rs.300 B) Rs.400 C) Rs.480 D) Rs.500 E) Rs.520
P : Q = 5 : 4, Q : R = 9 : 10 = ( 9 x 4 / 9 ) : ( 10 x 4 / 9 ) = 4 : 40 / 9.   So, P : Q : R = 5 : 4 : 40 /9 = 45 : 36 : 40   Sum of ratio terms is = ( 45 + 36 + 40 )=
