Question
Two types of Pulses cost Rs. 240/kg and Rs. 340/kg. In
what ratio should these be mixed so that the obtained mixture is sold at Rs. 324/kg to earn a profit of 20%?Solution
SP of the mixture = Rs. 324 Gain = 8% Therefore, CP of the mixture =324 × (100/120) = Rs. 270 Now, using the allegation method Type I Type II 240 340 270 70 30 Required Ratio = 7: 3
