Question

coffee costing rs.250 per kg was mixed with chicory costing rs.75 per kg in the ratio of 5:2 for a certain blend.If the mixture was sold at rs.230 per kg,find the gain or loss percent.

Answer 1

5:2 = 5 Kg of 1st variety and 2 Kg of 2nd variety

Total = (5+2) Kg = 7 kg

CP of 7 kg of mixture = (5*250)+(2*75) = ₹(1250+150) = ₹1400

CP of 1 kg of mixture = 1400/7 = ₹200

SP = ₹230 per kg

Sp > CP ; hence there is a gain.

Gain = (Sp – CP) = ₹(230–200) = ₹30

Gain % = (gain/CP * 100)%

=> 30/200*100 => 15%

Ans => 15% is the gain%
