Question

A man buys 20 kg of apples at 60 per kg and 30 kg of apples at 70 per kg.At what rate per kg should he sell them to gain 25%?​

Answer 1

Answer:

Cp of 1 kg = 60

Cp of 20 kg = 60*20 = 1200

Cp of 1 kg = 70

Cp of 30 kg = 70*30 = 2100

Total cp = 1200 +2100 = 3300

Profit = 25%

Profit% = profit /cp *100

25*3300 /100 = profit

825 = profit

SP = cp + profit = 3300 + 825 = ₹4125

Answer 2

Solution-

Total expenditure of the man =( 20 × Rs.60)+(30×Rs.70)

=Rs.1200+Rs.2100

=Rs.3300

Total weight of apples bought= 20 kg+30kg

=50kg

Gain required=25%of Rs.3300

=25/100×Rs.3300

=25×Rs.33

=Rs.825

Total selling price =Profit required+Cost price

=Rs.825+Rs.3300

=Rs.4125

Rate at which the apples should be sold to meet the requirement =Rs. 4125/50kg

=Rs.82.5/kg

Answer:Rs.82.5/kg is the rate at which the apples should be sold .
