# Alligation or Mixture - Aptitude Questions and Answers - in Hindi

 The ratio of two liquids in a mixture is 3 : 5 and that in another mixture is 6:1. In what ratio these two mixtures must be mixed so as to make the ratio of the two liquids 7:3? एक मिश्रण में दो द्रवों का अनुपात 3:5 है और दूसरे मिश्रण में 6:1 है । इन दो मिश्रणों को किस अनुपात में मिलाना चाहिए कि दो द्रवों का अनुपात 7:3 हो जाए? A) 44 : 61 B) 44 : 71 C) 44 : 81 D) 44 : 91 Correct Answer : 44 : 91 Explanation :By the rule of alligation: If two ingredients are mixed, then Quantity of cheaper/Quantity of dearer =[(C.P. of dearer) - (Mean price)] / (Mean price) - [(C.P. of cheaper)] i.e. (Cheaper Quantity):(Dearer quantity)= (d-m):(m-c). ratio of a liquid1 in mixture1, c=3/8 ratio of a liquid1 in mixture2, d=6/7 Mean ratio of a liquid1 or ratio of a liquid1 in resultant mixture, m= 7/10 Thus ,Required ratio = (6/7 - 7/10) / (7/10 - 3/8) = ((60-49)/70) / ((28-15)/40) =(11/70) / (13/40) =(11*40) / (70*13) =44 / 91 Post/View Answer Post comment Cancel Thanks for your comment.!
