Answer 1

Answer:

See the explanation.

Step-by-step explanation:

Selling desi chai for Rs. 25 per kg, there is a loss of 15%.

Hence, (100 - 15)% = 85% ≡ 25 or, 100% = $\frac{25\times 100}{85} = 29.412$ (cost price of desi chai per kg).

There is a gain of 25% by selling videshi chai  for Rs 35 per kg.

Hence, (100 + 25)% = 125% ≡ 35 or, 100% = 28 (cost price of videshi chai  per kg).

Let, it should be mixed in the ratio of x and y.

If we want to gain a profit of 35% by selling at 30.5 per kg, then (100 + 35)% = 135% ≡ 30.5 or, 100% = 22.593(cost price of the mixture per kg).

$\frac{29.412x + 28y }{x+y} = 22.593\\29.412x + 28y = 22.593x + 22.593y\\6.819x = 5.407y\\\frac{x}{y} = \frac{5407}{6819}$
