Answer 2

Answer:

The seller mixes two varieties of rice in 129:101 ratio.

Step-by-step explanation:

Let the seller mixes two varieties of rice in x:y ratio whose costs are rs 65 and rs 115 kg respectively. According to question by selling the mixture at rs 100 per kg, the seller made a profit of 15%.

The price of x kg rice = $65x$.

The price of y kg rice = $115y$.

Price of the mixture = $100(x+y)$.

$(65x+115y) *(1+\frac{15}{100}) = 100(x+y)\\\\ or , 3225y = 2525x\\\\or , x : y = 3225 : 2525\\\\or , x : y = 129 : 101$

The seller mixes two varieties of rice in 129:101 ratio.
