(600-300-150) (400-200-50) (1000-500-250) (200-100-50)

(400-200-50)

☀ (600-300-150) = 600 , 600 ÷ 2 = 300 , 300 ÷ 2 = 150 ☀ (400-200-50) = 400 , 400 ÷ 2 = 200 , 200 ÷ 2 = 100 but 50 is given which is odd ☀ (1000-500-250) = 1000 , 1000 ÷ 2 = 500 , 500 ÷ 2 = 250 ☀ (200-100-50) = 200 , 200 ÷ 2 = 100 , 100 ÷ 2 = 50
