Question

In what ratio must two kinds of tea worth ₹18 and ₹ 28 per kg be mixed so that by selling the mixture at ₹ 32 per kg ,there may be a gain of 20% ?​

Answer 1

Answer:Answer

Let the two kinds of tea bex and y.

Cost of the tea mixture will be 18x+28y.

Selling price after a profit will be 1.2(18x + 28y) = 21.6x + 33.6y

Equating both selling prices, 32x + 32y = 21.6x + 33.6y

Solving, we get

y,x as 10.4,1.6

​

which is nothing but 13,2

So, the ratio is 2:13.
