Two vessels A and B contain spirit and water in the ratio 5 : 2 and 7 : 6 respectively. Find the ratio in which these mixtures be mixed to obtain a new mixture in vessel C containing spirit and water in the ratio 8 : 5?
Two vessels A and B contain spirit and water in the ratio 5 : 2 and 7 : 6 respectively. Find the ratio in which these mixtures be mixed to obtain a new mixture in vessel C containing spirit and water in the ratio 8 : 5? Correct Answer 7 : 9
Given :
Two vessels A and B contain spirit and water in the ratio 5 : 2 and 7 : 6 respectively
The final mixture contains spirit and water in the ratio of 8 : 5.
Calculations :
Spirit in mixture A = 5/7 (spirit : water = 5 : 2)
Spirit in mixture B = 7/13 ((spirit : water = 7 : 6)
Spirit in final mixture of C = 8/13 ((spirit : water = 8 : 5)
Now using allegation method
