7:5 initial ratio of mixture ... aur hm jante h ki kitna bi mixture se nikale ..A aur B ka ratio same hi rhega... mtlb 9 ltr निकलने के बाद भी mixture का ratio same होगा... liquid A : liquid B 7 : 5 volume of A = 7/12 volume of B = 5/12 after mixing 9 ltr of liquid B liquid A : liquid B 7x : 9x = 16x final mixture means 4x = 9 ltr 16x = 36 ltr (total volume of mixture) therefore volume of Liquid A = 36* 7/12 =21 ltr answer....
