Question

. easha bought two varieties of rice, costing rs 50 per kg and rs. 60 per kg each, and mixed them in some ratio. then she sold the mixture at rs. 70 per kg, making a profit of 20%. what was the ratio of the mixture?

Answer 1

Selling price of the mixture = 70 and profit = 20%

Cost price of the mixture = 70×100/120=70×5/6
By applying alligation rule:

50(least price) 60(high price)
70 x (50/60) (new price *(least*high)
60-(175/3) : (175/3)-50

So ratio = 60−(175/3) : (175/3)-50
= 1 : 5
