A can give B 100 meters start and C 120 meters start in a kilometer race. How much start can B give C in a kilometer race?
Choose the correct answer:	A) 10.22 meters	B) 11.22 meters	C) 22.22 meters	D) 33.22 meters	E) None of these
Explanation:   A runs 1000 meters while B runs 900 meters and C runs 880 meters.   Therefore, B runs 900 meters while C runs 880 meters.   So, the number of meters that 22.22 meters runs when B runs 1000 meters = (1000 x 880)/900 = 977.778 meters   Thus, B can give 22.22 meters (1000 - 977.77) = 22.22 meters start   Answer: 22.22 meters
