Given :
Cost of each kind = Rs. 2, Rs. 3.5 , Rs. 4.8 per kg
Cost of mixture = Rs. 2.6 per kg.
To find : Ratio of three wheat = ?
Solution :
Using "Mixture and Allegation ", we get :
First type : Second type
2 3.5
2.6
-----------------------------------
3.5-2.6 : 2.6 - 2
0.9 : 0.6
9 : 6
3 : 2
Now,
Second type : Third type
3.5 4.8
2.6
------------------------------------------
4.8 - 2.6 : 3.5 - 2.6
2.2 : 0.9
22 : 9
So, combining both the ratios, we get
First type : Second type : third type
3 : 2
22 : 9
----------------------------------------------------------------------
66 : 44 : 18
33 : 22 : 9
Hence, the ratio would be 33:22:9.
