Q22. Two Vessels A And B Contain Spirit And Water Mixed In The Ratio 5:2 And 7:6 Respectively. Find The Ratio In Which These Mixture Be Mixed To Obtain A New Mixture In Vessel C Containing Spirit And Water

Let's expect C.P. Of spirit = Re. 1 in line with litre.

Spirit in 1 litre blend. Of A = 5/7 litre. So C.P of one litre mix in A = Re. Five/7.

Spirit in 1 litre blend. Of B = 7/thirteen litre. So C.P of 1 litre blend in B = Re. 7/13.

Spirit in 1-litre mix. Of C = 8/thirteen litre. So C.P. Of one litre blend in C = Re. 8/thirteen.

By rule of an allegation, we have required ratio X:Y.

(five/7) (7/thirteen)

(eight/13)

(1/thirteen) (9/ninety one)

So, required ratio = 1/13 : nine/91 = 7:9.
