Sam buys 40 kg of wheat at Rs. 6.25 per kg and 30 kg of wheat at Rs. 7 per kg. At what rate per kg should he sell the mixture to gain 5% on the whole?

Answer 1

Answer:

• 3.9 Rs/ Kg

Step-by-step explanation:

• 40kg of wheat at Rs 6.25/kg, Price= 250 (6.25 X 40)
• 30kg of wheat at Rs 7/kg, Price= 210 (7 X 30)
• Total Price= 250+210= 260
• Add 5% profit= 5% of 260= 13, 260+13= 273
• 273/70= 3.9 Rs/ Kg
