n what ratio should tea at 35 per kg be mixed with tea at 27per kg so that mixture may cost 30per kg? a) 7:2 b) 2:7 c) 3:5 d) 5:3 e) None of these.

Answer 2

Answer:

c) 3:5

Step-by-step explanation:

The average cost is 30

Let x kg of tea at Rs. 35/kg be mixed with y kg of tea at Rs. 27/kg

Total amount of tea = x + y kg

Average price = Rs. 30/kg

So, 35x + 27y = 30 (x + y)

Or 5x = 3y

Or x/y = 3/5
