a:b:c = 3:5:7
then a =(3x –45600), b= (7x+337600)
ratio= 24:59:167
(3x-45600) / (7x+337600) = 24/167
then (501x–7615200) = (168x – 8102400)
then =(501x-168x) = (8102400+7615200)
then = 333x = 15717600
then x = 47200
then A = 3x = 3*47200= 141600
then a =(3x –45600), b= (7x+337600)
ratio= 24:59:167
(3x-45600) / (7x+337600) = 24/167
then (501x–7615200) = (168x – 8102400)
then =(501x-168x) = (8102400+7615200)
then = 333x = 15717600
then x = 47200
then A = 3x = 3*47200= 141600
