 Question 33104: A and B are indirectly proportional to each other. When B = 120, A = 30. What is the value of A when B = 160.Found 2 solutions by mukhopadhyay, sarah_adam:Answer by mukhopadhyay(490)   (Show Source): You can put this solution on YOUR website!The question should read as "A and B are inversely proportional to each other" A=k/B (because they are inversely proportional to each other) 30=k/120 => k = 30*120 A = 30*120/B When B = 160, A = 30*120/160 = 360/16 = 45/2; Answer by sarah_adam(201)   (Show Source): You can put this solution on YOUR website!When A and B are inversely proportional A = K/B where K = constant Now when A = 30 and B = 120 then K = A*B K = 30*120 = 3600 No when B = 160 A = 3600/160 = 22.5
