Question

Sonu buys 40kg of wheat at rs.12.50 per kg and 30kg of wheat at rs. 14per kg. At what rate per kg he sell the mixture to gain 5% on the whole?

Answer 1

Sonu buys 40 kg of wheat at rs.12.50 per kg

so it's cost is = 40 × 12.5

= 500 rs

Sonu buys 30 kg of wheat at rs. 14 per kg

so it's cost = 30 × 14

= 420 rs

total wheat buys = 40 + 30

= 70 kg

total cost = 500 + 420

= 920 rs


profit must be ,

100 cost ------ 5 profit

920 cost ------- ?? profit



profit = 920 × 5 / 100

profit = 46 rs

so selling price = 920 + 46

= 966 rs


so price of mixture per kg = 966 / 70

= 13 .80 rs

Answer 2

Answer:

Step-by-step explanation:

Sonu buys 40 kg of wheat at rs.12.50 per kg

so it's cost is = 40 × 12.5

= 500 rs

Sonu buys 30 kg of wheat at rs. 14 per kg

so it's cost = 30 × 14

= 420 rs

total wheat buys = 40 + 30

= 70 kg

total cost = 500 + 420

= 920 rs

profit must be ,

100 cost ------ 5 profit

920 cost ------- ?? profit

profit = 920 × 5 / 100

profit = 46 rs

so selling price = 920 + 46

= 966 rs

so price of mixture per kg = 966 / 70

= 13 .80 rs
