Question

two varieties of coffee costing ₹250 per kg and ₹75 per kg were mixed in the ratio 5:2 for a certain blend .if the mixture was sold ₹230per kg ,find the gain and loss percent .

Answer 1

Cost of first variety = 250

Cost of second variety = 75

Ratio = 5:2

Selling price = 230

Sum of ratio = 5+2 = 7

Total coffee = 1 kg

Thus,

Quantity of first variety = 5*1/7 kg

= 5/7 kg

It's cost = 5*250/7

= 1250/7 rs

Quantity of second variety = 2*1/7 kg

= 2/7 kg

It's cost = 2*75/7

= 150/7 rs

Total cp = (1250/7) + (150/7)

= 1400/7

= rs. 200

Sp given = rs. 230

Thus, gain = rs. 30

Gain % = (30/200)*100

= 15%

Hope it helps :)
