3 varieties of rice costing 34.5/kg, 36.5/kg and 41.2/kg sold at 46.2/kg making a profit of 22.22%. In what ratio did the seller mix 3 of them? Need an explanation through alligations.

Calculate the CP by dividing 46.2 by 1.22
That'll be 37.7 I guess
Perform alligation on variety 2 and variety 3
Another alligation on variety 1 and variety 3
Add both the alligations that'll be your answer. For more details better go through the 3 variable alligation lecture

I think the best way is to go through the options. Doesn't this question have options?
