Question

Kantilal mixes 80 kg of sugar worth of Rs. 6.75 per kg with 120 kg worth of Rs. 8 per kg. At what rate shall he sell the mixture to gain 20%.

Answer 1

80 kg of sugar @6.5 rs/kg is 540 rs.

120 kg of sugar @8 rs/kg is 960 rs.

Total amount of sugar is 80+120= 200 kg

Total purchase amount is 540+960=1500

To sell his entire stock at 20% profit the vendor needs to sell it for 1500×120/100 = 1800 rs.

For 20 profit at entire stock he needs to sell per kg at 1800/200=9

The answer is 9rs/kg
