Question

Sonu buys 40 kg of wheat at Rs 12.50 per kg and 30 kg of wheat at Rs 14 per kg at what rate per kg soda sell the mixture to gain 5% on the wall

Answer 1

total price of wheat = 40*12.5 + 30*14
= 500 + 420 = 920/-

profit = 15/100 * 920 = 138/-

total quantity = 40 + 30 = 70 kg

price per kg = (920 + 138)/70= 1058/70
= Rs 15.11
