Answer» SUPPOSE he mixes T kg of brick powder in 5 kg of chili powder. Cost price of 5 kg of chili powder = Rs. 3000 × 5 = Rs. 15000 After mixing, total amount of mixture = (5 + T) kg Selling price of 1 kg of mixture = 3000 – 3000 × (5/100) = Rs. 2850 Selling price of (5 + T) kg of mixture = Rs. 2850 × (5 + T) = Rs. (14250 + 2850T) We know, Selling Price = Cost Price × (1 + (Profit Percentage)/100) (14250 + 2850T) = 15000 × (1+ 12/100) 14250 + 2850T = 16800 T = 2550/2850 = 0.895 ∴ 0.895 kg or 895 GRAMS of brick powder should be mixed. |
