(C) 4 years
(D) 5 years
(E) 6 years
answer: Stream of consciousness: Let the time be x years. Then (600 *3* x)/100 + (800*9*x)/(2*100) = 24

Required time = 4 years The answer is (C).

q: ? 370 860 1550 2440 3530
Options:
(A) 900
(B) 840
(C) 750
(D) 860
(E) 80
a: Stream of consciousness: 10^2 - 20 = 80
20^2 - 30 = 370
30^2 - 40 = 860
40^2 - 50 = 1550
50^2 - 60 = 2440
60^2 - 70 = 3530. The answer is (E).
