Robert and Luke are two brothers. Their father divides Rs.7 569 between them such that Robert's share at the end of 9 years is equal to Luke's share at the end of 11 years, compounded annually at the rate 5%. Luke's share was

(A) Rs.3 950

(C) Rs.3 969

(B) Rs.3 960

(D) Rs.3 990

If Luke got x, then

x*1.05^11 = (7569-x)*1.05^9
x = 3600
did both get the same rate of interest?
